A Design and Implementation of Active NetworkSocket ProgrammingK.L. Eddie Law, Roy LeungThe Edward S. Rogers Sr. Department of Electrical and Computer EngineeringUniversity of TorontoToronto, Canadaeddie@, roy.leung@utoronto.caAbstract—The concept of programmable nodes and active networks introduces programmability into communication networks. Code and data can be sent and modified on their ways to destinations. Recently, various research groups have designed and implemented their own design platforms. Each design has its own benefits and drawbacks. Moreover, there exists an interoperability problem among platforms. As a result, we introduce a concept that is similar to the network socket programming. We intentionally establish a set of simple interfaces for programming active applications. This set of interfaces, known as Active Network Socket Programming (ANSP), will be working on top of all other execution environments in future. Therefore, the ANSP offers a concept that is similar to “write once, run everywhere.” It is an open programming model that active applications can work on all execution environments. It solves the heterogeneity within active networks. This is especially useful when active applications need to access all regions within a heterogeneous network to deploy special service at critical points or to monitor the performance of the entire networks. Instead of introducing a new platform, our approach provides a thin, transparent layer on top of existing environments that can be easily installed for all active applications.Keywords-active networks; application programming interface; active network socket programming;I. I NTRODUCTIONIn 1990, Clark and Tennenhouse [1] proposed a design framework for introducing new network protocols for the Internet. Since the publication of that position paper, active network design framework [2, 3, 10] has slowly taken shape in the late 1990s. The active network paradigm allows program code and data to be delivered simultaneously on the Internet. Moreover, they may get executed and modified on their ways to their destinations. At the moment, there is a global active network backbone, the ABone, for experiments on active networks. Apart from the immaturity of the executing platform, the primary hindrance on the deployment of active networks on the Internet is more on the commercially related issues. For example, a vendor may hesitate to allow network routers to run some unknown programs that may affect their expected routing performance. As a result, alternatives were proposed to allow active network concept to operate on the Internet, such as the application layer active networking (ALAN) project [4] from the European research community. In the ALAN project, there are active server systems located at different places in the networks and active applications are allowed to run in these servers at the application layer. Another potential approach from the network service provider is to offer active network service as the premium service class in the networks. This service class should provide the best Quality of Service (QoS), and allow the access of computing facility in routers. With this approach, the network service providers can create a new source of income.The research in active networks has been progressing steadily. Since active networks introduce programmability on the Internet, appropriate executing platforms for the active applications to execute should be established. These operating platforms are known as execution environments (EEs) and a few of them have been created, e.g., the Active Signaling Protocol (ASP) [12] and the Active Network Transport System (ANTS) [11]. Hence, different active applications can be implemented to test the active networking concept.With these EEs, some experiments have been carried out to examine the active network concept, for example, the mobile networks [5], web proxies [6], and multicast routers [7]. Active networks introduce a lot of program flexibility and extensibility in networks. Several research groups have proposed various designs of execution environments to offer network computation within routers. Their performance and potential benefits to existing infrastructure are being evaluated [8, 9]. Unfortunately, they seldom concern the interoperability problems when the active networks consist of multiple execution environments. For example, there are three EEs in ABone. Active applications written for one particular EE cannot be operated on other platforms. This introduces another problem of resources partitioning for different EEs to operate. Moreover, there are always some critical network applications that need to run under all network routers, such as collecting information and deploying service at critical points to monitor the networks.In this paper, a framework known as Active Network Socket Programming (ANSP) model is proposed to work with all EEs. It offers the following primary objectives.• One single programming interface is introduced for writing active applications.• Since ANSP offers the programming interface, the design of EE can be made independent of the ANSP.This enables a transparency in developing andenhancing future execution environments.• ANSP addresses the interoperability issues among different execution environments.• Through the design of ANSP, the pros and cons of different EEs will be gained. This may help design abetter EE with improved performance in future.The primary objective of the ANSP is to enable all active applications that are written in ANSP can operate in the ABone testbed . While the proposed ANSP framework is essential in unifying the network environments, we believe that the availability of different environments is beneficial in the development of a better execution environment in future. ANSP is not intended to replace all existing environments, but to enable the studies of new network services which are orthogonal to the designs of execution environments. Therefore, ANSP is designed to be a thin and transparent layer on top of all execution environments. Currently, its deployment relies on automatic code loading with the underlying environments. As a result, the deployment of ANSP at a router is optional and does not require any change to the execution environments.II. D ESIGN I SSUES ON ANSPThe ANSP unifies existing programming interfaces among all EEs. Conceptually, the design of ANSP is similar to the middleware design that offers proper translation mechanisms to different EEs. The provisioning of a unified interface is only one part of the whole ANSP platform. There are many other issues that need to be considered. Apart from translating a set of programming interfaces to other executable calls in different EEs, there are other design issues that should be covered, e.g., • a unified thread library handles thread operations regardless of the thread libraries used in the EEs;• a global soft-store allows information sharing among capsules that may execute over different environmentsat a given router;• a unified addressing scheme used across different environments; more importantly, a routing informationexchange mechanism should be designed across EEs toobtain a global view of the unified networks;• a programming model that should be independent to any programming languages in active networks;• and finally, a translation mechanism to hide the heterogeneity of capsule header structures.A. Heterogeneity in programming modelEach execution environment provides various abstractions for its services and resources in the form of program calls. The model consists of a set of well-defined components, each of them has its own programming interfaces. For the abstractions, capsule-based programming model [10] is the most popular design in active networks. It is used in ANTS [11] and ASP [12], and they are being supported in ABone. Although they are developed based on the same capsule model, their respective components and interfaces are different. Therefore, programs written in one EE cannot run in anther EE. The conceptual views of the programming models in ANTS and ASP are shown in Figure 1.There are three distinct components in ANTS: application, capsule, and execution environment. There exist user interfaces for the active applications at only the source and destination routers. Then the users can specify their customized actions to the networks. According to the program function, the applications send one or more capsules to carry out the operations. Both applications and capsules operate on top of an execution environment that exports an interface to its internal programming resources. Capsule executes its program at each router it has visited. When it arrives at its destination, the application at destination may either reply it with another capsule or presents this arrival event to the user. One drawback with ANTS is that it only allows “bootstrap” application.Figure 1. Programming Models in ASP and ANTS.In contrast, ASP does not limit its users to run “bootstrap” applications. Its program interfaces are different from ANTS, but there are also has three components in ASP: application client, environment, and AAContext. The application client can run on active or non-active host. It can start an active application by simply sending a request message to the EE. The client presents information to users and allows its users to trigger actions at a nearby active router. AAContext is the core of the network service and its specification is divided into two parts. One part specifies its actions at its source and destination routers. Its role is similar to that of the application in ANTS, except that it does not provide a direct interface with the user. The other part defines its actions when it runs inside the active networks and it is similar to the functional behaviors of a capsule in ANTS.In order to deal with the heterogeneity of these two models, ANSP needs to introduce a new set of programming interfaces and map its interfaces and execution model to those within the routers’ EEs.B. Unified Thread LibraryEach execution environment must ensure the isolation of instance executions, so they do not affect each other or accessThe authors appreciate the Nortel Institute for Telecommunications (NIT) at the University of Toronto to allow them to access the computing facilitiesothers’ information. There are various ways to enforce the access control. One simple way is to have one virtual machine for one instance of active applications. This relies on the security design in the virtual machines to isolate services. ANTS is one example that is using this method. Nevertheless, the use of multiple virtual machines requires relatively large amount of resources and may be inefficient in some cases. Therefore, certain environments, such as ASP, allow network services to run within a virtual machine but restrict the use of their services to a limited set of libraries in their packages. For instance, ASP provides its thread library to enforce access control. Because of the differences in these types of thread mechanism, ANSP devises a new thread library to allow uniform accesses to different thread mechanisms.C. Soft-StoreSoft-store allows capsule to insert and retrieve information at a router, thus allowing more than one capsules to exchange information within a network. However, problem arises when a network service can execute under different environments within a router. The problem occurs especially when a network service inserts its soft-store information in one environment and retrieves its data at a later time in another environment at the same router. Due to the fact that execution environments are not allowed to exchange information, the network service cannot retrieve its previous data. Therefore, our ANSP framework needs to take into account of this problem and provides soft-store mechanism that allows universal access of its data at each router.D. Global View of a Unified NetworkWhen an active application is written with ANSP, it can execute on different environment seamlessly. The previously smaller and partitioned networks based on different EEs can now be merging into one large active network. It is then necessary to advise the network topology across the networks. However, different execution environments have different addressing schemes and proprietary routing protocols. In order to merge these partitions together, ANSP must provide a new unified addressing scheme. This new scheme should be interpretable by any environments through appropriate translations with the ANSP. Upon defining the new addressing scheme, a new routing protocol should be designed to operate among environments to exchange topology information. This allows each environment in a network to have a complete view of its network topology.E. Language-Independent ModelExecution environment can be programmed in any programming language. One of the most commonly used languages is Java [13] due to its dynamic code loading capability. In fact, both ANTS and ASP are developed in Java. Nevertheless, the active network architecture shown in Figure 2 does not restrict the use of additional environments that are developed in other languages. For instance, the active network daemon, anted, in Abone provides a workspace to execute multiple execution environments within a router. PLAN, for example, is implemented in Ocaml that will be deployable on ABone in future. Although the current active network is designed to deploy multiple environments that can be in any programming languages, there lacks the tool to allow active applications to run seamlessly upon these environments. Hence, one of the issues that ANSP needs to address is to design a programming model that can work with different programming languages. Although our current prototype only considers ANTS and ASP in its design, PLAN will be the next target to address the programming language issue and to improve the design of ANSP.Figure 2. ANSP Framework Model.F. Heterogeneity of Capsule Header StructureThe structures of the capsule headers are different in different EEs. They carries capsule-related information, for example, the capsule types, sources and destinations. This information is important when certain decision needs to be made within its target environment. A unified model should allow its program code to be executed on different environments. However, the capsule header prevents different environments to interpret its information successfully. Therefore, ANSP should carry out appropriate translation to the header information before the target environment receives this capsule.III. ANSP P ROGRAMMING M ODELWe have outlined the design issues encountered with the ANSP. In the following, the design of the programming model in ANSP will be discussed. This proposed framework provides a set of unified programming interfaces that allows active applications to work on all execution environments. The framework is shown in Figure 2. It is composed of two layers integrated within the active network architecture. These two layers can operate independently without the other layer. The upper layer provides a unified programming model to active applications. The lower layer provides appropriate translation procedure to the ANSP applications when it is processed by different environments. This service is necessary because each environment has its own header definition.The ANSP framework provides a set of programming calls which are abstractions of ANSP services and resources. A capsule-based model is used for ANSP, and it is currently extended to map to other capsule-based models used in ANTSand ASP. The mapping possibility to other models remains as our future works. Hence, the mapping technique in ANSP allows any ANSP applications to access the same programming resources in different environments through a single set of interfaces. The mapping has to be done in a consistent and transparent manner. Therefore, the ANSP appears as an execution environment that provides a complete set of functionalities to active applications. While in fact, it is an overlay structure that makes use of the services provided from the underlying environments. In the following, the high-level functional descriptions of the ANSP model are described. Then, the implementations will be discussed. The ANSP programming model is based upon the interactions between four components: application client , application stub , capsule , and active service base.Figure 3. Information Flow with the ANSP.•Application Client : In a typical scenario, an active application requires some means to present information to its users, e.g., the state of the networks. A graphical user interface (GUI) is designed to operate with the application client if the ANSP runs on a non-active host.•Application Stub : When an application starts, it activates the application client to create a new instance of application stub at its near-by active node. There are two responsibilities for the application stub. One of them is to receive users’ instructions from the application client. Another one is to receive incoming capsules from networks and to perform appropriate actions. Typically, there are two types of actions, thatare, to reply or relay in capsules through the networks, or to notify the users regarding the incoming capsule. •Capsule : An active application may contain several capsule types. Each of them carries program code (also referred to as forwarding routine). Since the application defines a protocol to specify the interactions among capsules as well as the application stubs. Every capsule executes its forwarding routine at each router it visits along the path between the source and destination.•Active Service Base : An active service base is designed to export routers’ environments’ services and execute program calls from application stubs and capsules from different EEs. The base is loaded automatically at each router whenever a capsule arrives.The interactions among components within ANSP are shown in Figure 3. The designs of some key components in the ANSP will be discussed in the following subsections. A. Capsule (ANSPCapsule)ANSPXdr decode () ANSPXdr encode () int length ()Boolean execute ()New types of capsule are created by extending the abstract class ANSPCapsule . New extensions are required to define their own forwarding routines as well as their serialization procedures. These methods are indicated below:The execution of a capsule in ANSP is listed below. It is similar to the process in ANTS.1. A capsule is in serial binary representation before it issent to the network. When an active router receives a byte sequence, it invokes decode() to convert the sequence into a capsule. 2. The router invokes the forwarding routine of thecapsule, execute(). 3. When the capsule has finished its job and forwardsitself to its next hop by calling send(), this call implicitly invokes encode() to convert the capsule into a new serial byte representation. length() isused inside the call of encode() to determine the length of the resulting byte sequence. ANSP provides a XDR library called ANSPXdr to ease the jobs of encoding and decoding.B. Active Service Base (ANSPBase)In an active node, the Active Service Base provides a unified interface to export the available resources in EEs for the rest of the ANSP components. The services may include thread management, node query, and soft-store operation, as shown in Table 1.TABLE I. ACTIVE SERVICE BASE FUNCTION CALLSFunction Definition Descriptionboolean send (Capsule, Address) Transmit a capsule towards its destination using the routing table of theunderlying environment.ANSPAddress getLocalHost () Return address of the local host as an ANSPAddress structure. This isuseful when a capsule wants to check its current location.boolean isLocal (ANSPAddress) Return true if its input argument matches the local host’s address andreturn false otherwise.createThread () Create a new thread that is a class ofANSPThreadInterface (discussed later in Section VIA “Unified Thread Abstraction”).putSStore (key, Object) Object getSStore (key) removeSStore (key)The soft-store operations are provided by putSStore(), getSSTore(), and removeSStore(), and they put, retrieve, and remove data respectively. forName (PathName) Supported in ANSP to retrieve a classobject corresponding to the given path name in its argument. This code retrieval may rely on the code loading mechanism in the environment whennecessary.C. Application Client (ANSPClient)boolean start (args[])boolean start (args[],runningEEs) boolean start (args[],startClient)boolean start (args[],startClient, runningEE)Application Client is an interface between users and the nearby active source router. It does the following responsibilities.1. Code registration: It may be necessary to specify thelocation and name of the application code in some execution environments, e.g., ANTS. 2. Application initialization: It includes selecting anexecution environment to execute the application among those are available at the source router. Each active application can create an application client instance by extending the abstract class, ANSPClient . The extension inherits a method, start(), to automatically handle both the registration and initialization processes. All overloaded versions of start() accept a list of arguments, args , that are passed to the application stub during its initialization. An optional argument called runningEEs allows an application client to select a particular set of environment variables, specified by a list of standardized numerical environment ID, the ANEP ID, to perform code registration. If this argument is not specified, the default setting can only include ANTS and ASP. D. Application Stub (ANSPApplication)receive (ANSPCapsule)Application stubs reside at the source and destination routers to initialize the ANSP application after the application clients complete the initialization and registration processes. It is responsible for receiving and serving capsules from the networks as well as actions requested from the clients. A new instance is created by extending the application client abstract class, ANSPApplication . This extension includes the definition of a handling routine called receive(), which is invoked when a stub receives a new capsule.IV. ANSP E XAMPLE : T RACE -R OUTEA testbed has been created to verify the design correctnessof ANSP in heterogeneous environments. There are three types of router setting on this testbed:1. Router that contains ANTS and a ANSP daemonrunning on behalf of ASP; 2. Router that contains ASP and a ANSP daemon thatruns on behalf of ANTS; 3. Router that contains both ASP and ANTS.The prototype is written in Java [11] with a traceroute testing program. The program records the execution environments of all intermediate routers that it has visited between the source and destination. It also measures the RTT between them. Figure 4 shows the GUI from the application client, and it finds three execution environments along the path: ASP, ANTS, and ASP. The execution sequence of the traceroute program is shown in Figure 5.Figure 4. The GUI for the TRACEROUTE Program.The TraceCapsule program code is created byextending the ANSPCapsule abstract class. When execute() starts, it checks the Boolean value of returning to determine if it is returning from the destination. It is set to true if TraceCapsule is traveling back to the source router; otherwise it is false . When traveling towards the destination, TraceCapsule keeps track of the environments and addresses of the routers it has visited in two arrays, path and trace , respectively. When it arrives at a new router, it calls addHop() to append the router address and its environment to these two arrays. When it finally arrives at the destination, it sets returning to false and forwards itself back to the source by calling send().When it returns to source, it invokes deliverToApp() to deliver itself to the application stub that has been running at the source. TraceCapsule carries information in its data field through the networks by executing encode() and decode(), which encapsulates and de-capsulates its data using External Data Representation (XDR) respectively. The syntax of ANSP XDR follows the syntax of XDR library from ANTS. length() in TraceCapsule returns the data length, or it can be calculated by using the primitive types in the XDRlibrary.Figure 5. Flow of the TRACEROUTE Capsules.V. C ONCLUSIONSIn this paper, we present a new unified layered architecture for active networks. The new model is known as Active Network Socket Programming (ANSP). It allows each active application to be written once and run on multiple environments in active networks. Our experiments successfully verify the design of ANSP architecture, and it has been successfully deployed to work harmoniously with ANTS and ASP without making any changes to their architectures. In fact, the unified programming interface layer is light-weighted and can be dynamically deployable upon request.R EFERENCES[1] D.D. Clark, D.L.

The paper also discussed the need to open the roof holes, windows, and with other design with complex forms . The corresponding simple approximate calculation method and the structure treatment also described in this paper.Keywords : sloping roof;folded plate; along plane load;vertical plane load1. IntroductionIn recent years, reinforced concrete slope of the roof has been very common seen, the correct method of it’s design need establish urgently It’s target is to abolish or reduce the roof beams and columns, to obtain big room and make the roof plate "clean ". This not only benefits tructure specialty itself but also to the design of the building professionals to develop new field, and ultimately to allow users, property developers benefited,and so it has far-reaching significance.In the common practice engineering practice, a designer in the calculation of the mechanical model often referred sloping roof as vertical sloping roof under the projection plane Beam, or take level ridge, ramps ridge contour as a framework and increase unnecessary beam and tilt column . In fact ,the stress is similar between General square planar housing, double slope, multi-slope roof and arch, shell.Ping and oblique ridge are folded plate like “A”, whether layout beams and columns, its ridge line of the deformation pattern is different from the framework fundamentally. All these method will make the difference between calculation results and real internal structure force. During the construction process, housing backbone, plate bias department template has complex shapes, multi-angle bars overlap, installation and casting is very difficult. These projects are common in construction and is a typical superfluous. Some scholars use the elastic shell theory to analyze folded plate roof、internal force and deformation, reveals the vertical loads law of surrounding the base is neither level rise nor the vertical displacement which to some extent reflects the humps and shell’s features .But assume that boundary conditions which is very different from general engineering actual situation and covered the eaves of a vertical cross-settlement and bottom edge under the fundamental characteristics of rally, so it is not for general engineering design .2. Outlines of MethodsFor most frequently span, the way to cancel the backbone of housing, didn’t add axillary often. But in the periphery under the eaves to the framework need established grid-beam or beams over windows. For long rectangular planar multi-room, multi-column, building professionals in a horizontal layout of the partition wall between each pair of columns and the direction set deep into the same thickness width have possession of a gathering of the rafah beam profiles . Pull beam above has a two-slope roof plate affixed sloping beams expect smaller span. For residential,if it has no needs according construction professional, we will be able to achieve within the household no ceiling beams exposed, see figure 1. Similar lattice theory, this approach emphasizes the use of axial force component effe ct, But is different with the truss because it’s load distribution along the bar not only single but also along the axis of the plate. Generally each plate has force characteristics of folded plate, for bear gravity at the roof, wind, earthquake loads, caused the plate along with the internal force components, each plate is equivalent to strengthen the thin flange beams .Among vertical bearing , it is thin-walled beams anti-edge horizontal component to balance Wang thrust formed by arch shell effect. When plates bear the the vertical component load, each plate is equivalent to a solid edge embedded multilateral bearing plates .The design feature of this method is establish and perfect the sloping roof of the arch, folded plate system Consciously, at top of the roof, using a minimal level of rafah balance beam ramp at the level of thrust.It’s calculation methods can be divided into hand algorithm and computer paper, this paper focus on the hand algorithm.Hand algorithm take the single-slope plate of sloping roof plate as slider , through approximate overall analysis, Simplified boundary conditions of determine plate,solving load effect along level and vertical plane, Internal forces of various linear superposition under the condition of assumption of normal straight, testing stability and integrated reinforcement. The method pursuit of operational, use general engineer familiar calculation steps to address more complex issues.This method is suitable for the framework structure, little modifications also apply to masonrystructure or Frame-wall structure. General arch structure have good anti-seismic performance, if designed properly, the sloping roof will also do so. In this paper the pseudo-static is used to analysis earthquake effects.3. Analysis and Design for Along Plane Effect of LoadsFirst regard to cross profile of figure 1,we analysis equal width rectangular parts of long trapezoidal panels 1、2. as for approximate calculation,it is take plane loads along plane as a constant just like four rectangular plate can be simplified to one-way slab,we take along to long unit width narrow structure as analysis object ,take hinged arch model shown in figure 2.图2a图3a图2b图3b图2c图3cIn Figure 2 the right supports vertical linkage representatives roof beams supporting role, ramps connecting rod on behalf of the board itself thin beam reaction effect which is virtual and approximate equivalent. We would like to calculate two anti-bearing.Because the total pressure of physical project through two plate roof beams and transfer to the ends column, So Anti two numerical difference can be seen as two plates bear along with the plane load and roof beams bear the vertical load pressure.

Central Plate vertical stiffness small, in general gravity load of roughly symmetric midpoint only next movement happened possible, Therefore, the model used parallel two-link connection.

Moreover,the triangle area is small As approximate calculation, such direct-use rectangular plate slope calculation is more convenient and not obvious waste. The method of solve two load distribution of plate three is same as the solution of Long trapezoidal plate area just make the change of x and y、L2 and L3 in figure 1.The actual profile is part III-III shown in figure 1A B C图4a图4b BDFigure 4 is vertical launch plan and bear load portfolio value of roof ramp shown in Figure 1 to analysis inclined plate and the internal forces of the anti-bearing column . in the figure hypotenuse is oblique roof equal to strengthen frame, Similar wind ramp truss rod and the next edge portfolio, could form the dark truss system ,while long rectangular plate can be seen as part of thin-walled beams, which could also be seen as truss. Therefore, we called roof boarding the plane formed a "thin-walled beam-truss" system, in concrete theory, between the truss and the b eam have no natural divide . it’s no need hand count accurate internal forces and bearing force to such a joint system, Because on the one hand span more, big bending stiffness structure sensitive to the bearing uneven subsidence and have to stay safe reserves; on the other hand it has high cross-section, by increasing reinforced to increase capacity on the cost impact is not significant. Specific algorithm is: Single-ramp calculate by simple cradle, Multi-Span ramp’s bending moment, shear, and supporting anti-edge use the calculate value by the possible maximum numerical control methods, Moment is calculate by simple cradle two sides of supports middle Shear, negative moment and support force calculate according to bearing this continuous, two-hinged, about two span take the largest one. Pin-Pin bearing shear force that is supported by the inter-simple calculate according to simple cradle. But in this method the location of the various internal force’s safety level is uneven expansion, appropriate adjustmen t should be made is late calculation. No mater f the triangular or rectangular part of plate, Thin-plane bending rebar can get by method of moment right boards from the bottom point for the moment distance whichassigned to the eaves or roof. The author believe it has no necessary control number of reinforcement according to smallest beams reinforced rate. On the rim of triangle equivalent to ramp strut can shear entirety. when consider the end is weak can properly reinforced its roof beam below the reinforcement. If shear required stirrup in the rectangular part of thin-walled, should superposition to the beam, generally it’s no need to intentionally imaginary abdominal strengthening reinforcement at rod position.4. Calculation and Design of Pull Beam and Roof BeamsBy column in figure 1 marked calculated value of supporting force and their level of vertical component, horizontal component of the total force multiplied by the cosine of angle. Take column A as example, the first footnotes in R A2 is column number, the first footnotes represent the force generated by the panel two. Their horizontal component balanced by triangle three under the eaves of beams. horizontal component of intermediate support reaction is balanced by the two-level pull beam in deep direction. Then pull beam and above the sloping beams constitutes steel Arch. Because of the existence of antisymmetric load, bilateral role in the anti-power-level components may be inconsistent and pull beam should take the average lag. consider the support impact of uneven settlement, the level pull beam design should take bigger value.Roof beams general under four internal forces: First of the above is levels Rally, The second is axial force generated when oblique roofing in the flange plate plane bending. The third is the vertical load to bear as the roof slab edge beams under bending moment, shear ,like board supported by multi-faceted, Actual force is smaller than bear calculated by one-way plate N b,Fourth is the effect of lateral framework of internal forces .it should linear superposition ,Composite Reinforced, in the situation of weight Load, span and the small dip, checking computations should be took for tension beams cracking, appropriate intensify the section, with fine steel, including the side beams of steel beams rafah terminal should take two meander anchorage,just like letter L With ng as 10d long bends, meander 135 degrees angle and put pull beam intersection with the vertical reinforcement column touting the Meander overcast horn.This paper take model in figure 1 as example, ignore tigers window , 4 sloping roof are 35 o angle, the length of roof slab dimensions are shown in figure 4. Plate unit area quality is 350kg/m2,Overhaul live load is 0.50 kN/m2, Pressure standard of windward side is 0.21 kN/m2, Leeward face is -0.45 kN/m2, Design value of roof horizontal seismic acceleration is 0.1g, Calculate the bearing capacity limit by standardizing, Considered separately with and without seismic load effect of the combination basic design value,we use combination of without earthquake force through compare，Load calculation and analysis results of every position shown in table 1:5. Analysis and Design for Roof of the Vertical Loads Under Sloping RoofSlabs as a Multilateral Support PlateFolded plate structure has character of “unified of borad and frame”: General intersection of each pair of ramps are for mutual support, both sides of the transition line’ plate can be counted dogleg small rotation and transmission, distribution Moment.Under load control which is the role of gravity the two sloping geometry load roughly symmetrical occasions, there is no corner at symmetry capital turning point, Approximate seen as the plate embedded solid edge.if take out a distance by plate of eaves, plate of inside ridge also formation to negative moment,and long roof slabs in the plate sloping beams department and neighbor plate linked together, these all can be approximated as embedded-plate edge to process.For antisymmetric load like horizontal seismic load,the Ping roof should be treated as shear,but it is not control load usually. Plate final design moment value is the status of various unfavorable combination of linear superposition, from the cross-sectional direction plate reinforced by the columns, Reference, balance the require of concrete deep beams of tectonic, upper plate for Moment of negative reinforcement should be reinforced at all or an entire cross-leader, as they also serve as a deep beam distribution lumbartendons or stirrup. plate in the bottom vertical with reinforcement eaves, Negative reinforcementin accordance with their respective calcualte requirements,and it is different after superpositionstirrups requirementBoth sides of "stirrup" in this situation cann’t linked at awnings edge follow shape “U”, can bebent to shape "L" follow upper and down direction,legnth of packs could equal to thickness ofplate.It should enhenced at the node of ramp at the intersection appropriately. It recommended thatuse swagger tectonic shown as in Figure 5 considing simple structure without axillary at thesituation of Cloudy angle without pull. To ensure all reinforced Installing accuracy, Few of therhombus with the supports and rebar stirrups could be added to formed positioning Skeleton atstrengthening reinforced department in the figure, Let two later installed sloping steel plate tie toits lashing,designers should use a three-dimensional geometric method to accurately calculate thediamond stirrups limb edge length and Forming a swagger construction plans6. Calculating and processing of open window and hole in sloping roofAssume the plate in figure 6 has a big hole whose wideth is b ,height is h 0 ,assuming that tungcenter along with the plane bending moment, shear, respectively are M and V through overall calculation, use vierendeel calculation method get about middle cave:1XO MM T τ= 2NR MM T τ=3113312h V V h h =+ 0XO NR M M M V h --= Where I 1、I 2 、I respectively represent upp er and down plate limb’s Section moment of inertia anddouble limbs section moment of inertia.while Edge Moment by hole is:1113I M V b M α=+ 2212I M V b M μ=+not very big by the hole, close to the neutral axis in most cases overall, under the no-hole design of the reinforced the opening hole after the plane can meet the demands by calculation,under the no-hole design of the reinforced the opening hole after the plane can meet the demands by calculation.General tiger win dow’s form prominent roof Facade which a hole had opened up and the other faces a concrete slab closed.when analysis of vertical slab roof slab surface loads ,compare with without windows and roof slabs hole window sheet increased load. profiles of window’s folded plate form make it reduce the bending stiffness compare with without hole roof board, But with the profile hole edge which parallel to the vertical plate is a partial increase in bending stiffness. In the absence of the vertical plate window subordinate legislation should have upturns beam to increase stiffness of the surrounding caves near.in this way i can temporarily ignore the plate stiffness variation acording to the actual load, size and boundary conditions by entities plate to calculate psitive and negative moment and further processing nodes.it should point out that theRoof ramp layout hole edge ideal location is near the plate-bending line, especially in the open side of the window because it was cut down byvertical transmission line of the moment. If the roof slab roof beams department no outward roof then the actual plate-bending force on the line near the roof beam reversed also true, Because of this architects should strive for when determine oosition of tiger position take appropriate care.When pin tung far away from line-bending window wall and roofing in the intersection must bear folded plate and transmission moment, but compare with plate without hole its capacity is weaken surely,and it’s node turn into weak parts. To fill thy judgment and calculation errorstwo panels can be double reinforcement. When the hole is less than line-bending scope should increase negative reinforcement around to keep overall security plate bearing capacity. To ensure steel plate in place accuratly,also should use positioning stirrups and longitudinal reinforcement constitute skeleton similar as figure 5. Hoop end within vertical bars should be strengthen steel and end cave corner should be harvested more than one anchor length to make sure that bottom of the cave 4 tensile stress concentration.7. Stabilize Roof SlopeIn China's V-shaped folded plate structure design norms,the method prevent both sides of theflanges at local instability is limit its generous ratio,This requirement come from the use of isotropic plate buckling theory analysis. In research the flanges outside instability in critical state, the boundary conditions of winglets suppose as freedom outside, fixed interior, pre - and post-hinged on both sides,the situation plates subjected to the bending stress to solve width and height ratio corresponding with the critical pressure compressive stress. When the grade of concreteIs C30,the limit of width and height(b/t)ratio is 47, take 35 as stress non-normative value. Concrete elastic modulus and strength levels is not a linear relationship if use high-strength concrete other study should be taken. In the actual slope roof only a long row to the middle plate bearing plate outside may receive pressure. And here is just the pouringplate affixed roof sloping beams and horizontal pull beam cast together.Have no possible of rollover and foreign rising displacement. norms limited of folded plate span is 21m. roof below and the vertical column spacing generally much smaller it. And the board which into one with roof beams changed boundary conditions of plate, anti-great instability role also very big. For other locations ramp vertical compression edge May also set up the appropriate plate edge beams all these method will receive beyond the norms of redundant safety. Taking into account the plate shear plane, while the vertical direction of the load caused the exit plane effects, Therefore, the grasp of security of caution should cautious. This paper proposed ramp thickness not less than to the short span of 1 / 35 which also conform to design experience of generally confined SLABS, Concrete should graded between C25 and C35 while Steel should I or class II.puter Calculation Method of Local Sloping Roof Structure andOverall ICC of Overall StructureAny calculate software with inclined plate shell modules and the modules bar structural finite element can calculation of competent sloping roof. Shell element of each node have 3 membrane freedom and three panels freedom and can analysis the plane board and internal forces Of out-of-plane effects. However, the current prevalence of certain spatial structure finite element computer program which although have shell model but some are not inclined plate, some not right at the same plane, the stress state and foreign integrated reinforcement are not perfect. Withstructures becoming more diverse, complex and ramp space problems often encountered. Such software should expand its pre - and post-processing functions for conversion of shell element stiffness matrix and loading vector in the direction of freedom and further analysis of ramp space, the space of concrete against stress integrated reinforcement. In a fundamental sense manual method and the finite element method are interchangeable but the result may be very different. As long as layout roof component as this concept,then use the software to calculate can fast, precise, to achieve this goal of this paper.From the eaves to the roof elevation areas, the whole roof of anti-lateral stiffness lower than mutation, quality small than lower,this could not easy to simulate in calculation of whole housing. At the top construction of the seismic as higher-mode response which is also whiplash effect, the earthquake-lateral force may be abnormal and have effect on under layers. Therefore, in the partial hand count roof occasions when take ICC analysis to the overall structure, it proposed roof layer use model of tilt rod ramp support to reduce effect on the overall results distortion.If use software with function of space ramp handling and sloping roof modeling with shell element,all will be wrapped from top to bottom. Top results can be directly used and the distortion of the overall impact would cease to exist.10. Conclusion1）Concrete ramps, side beams in different directions superposition of internal forces, reinforced and ramp stability, the hole limits all to be do in-depth study related this research. Similar typical problems are top floor of structural transformation layer and box-type base box side wall all their research results can be used to adopt.It’s a important method do observation on project; finite element analysis ICC will be more economical, practical and popular. Currently existing completed sloping roof no matter the subjective designers use what kind of assumptions and analysis and whether reinforcement is reasonable as long as the overall structure of the objective reality, create a space folded plate and the arch system that their current work state can be used to summarize and draw upon.2）This structure forms make a new world of design concept of use the top floor and impact on people's living habits.The economic, social benefits it taked will gradually revealed,however it need interaction of architectural and structural professionals and People’s awareness andinformation and even real estate management policies and other support aspects.This method is hard for structure professional,some specific details have no norms to follow at present. This is the challenges sructure staff faced and also the happy exist.references[1]Francis D.K.Ching A Visual Dictionary of Architecture, International Thomson Publishing Inc. 1997.[2]Jiang Fengqing :internal forces of Simply supported two-way pack square plate, Civil Engineering Journal,1982(2)[3]Lai Mingyuan.Zhang Guxin:Deflection and internal forces of Simple peripheral portfolio folded plate roof, Civil Engineering Journal,1992(2)[4] ]Lai Mingyuan: Deflection and internal forces of Simple flattened four folded plate roof slope, Civil Engineering Journal, 1995(1)[5]Li Kaixi.Cui Jia:Local Stability About Yan Beam, Building Structures ,1996(1) [6]user manuals and technical conditions of Multi-storey high-rise building and the space finite element structural analysis and design software SATWE, PKPM CAD department of China Building Research Academy[7]Chen Xinghui.Lin Yuankun: Several calculation problems in the design of V-folded plate roof , Scientific publishing house,1985[8]current building structure norms, China Construction Industry Press,2002译文：钢筋混凝土坡屋顶的结构设计简介：本文对于现浇钢筋混凝土坡屋顶，尤其是常见的住宅结构，指出实际工程中常见的设计错误及问题。

The affordability of housing affects the ability of the elderly to afford other necessities of life such as food and medical care. Housing that is located near hospitals and doctors, shopping, transportation, and recreational facilities can facilitate access to services that can enhance the quality of life. Housing can also be a place of memories of the past and a connection to friends and neighbors. Housing with supportive features and access to services can also make it possible for persons to age in place. In this session, we will be examining housing problems andoptions for the elderly. Along the way, we will be testing your housing IQ with a series of questions and exercises.2. Housing Situation of Older PersonsHow typical is the housing situation of the olders?We will begin by examining five areas :（1）Prevalence of home ownership （2）Length of stay in current residence （3）Living arrangements （4）Attachments of older persons to where they live （5）Moving behavior.With whom older persons live can influence housing affordability, space needs, and the ability to age in place. About 54% of older persons live with their spouses, 31% live alone, almost 13% live with related persons other than their spouse and about 2% live with unrelated persons. With increasing age, older persons (primarily women) are more likely to live alone or with a relative other than a spouse. Frail older women living alone are the persons most likely to reside in homes with ‘extra’ rooms and to need both physically supportive housing features and services to "age in place". This segment of the population is also the group most likely to move to more supportive housing settings such as assisted living.Many older persons have strong psychological attachments to their homes related to length of residence. The home often represents the place where they raised their children and a lifetime of memories. It is also a connection to an array of familiar persons such as neighbors and shopkeepers as well as near by places including houses of worship, libraries and community services. For manyolder persons, the home is an extension of their own personalities which is found in the furnishings . In addition, the home can represent a sense of economic security for the future, especially for homeowners who have paid off their mortgages. For owners, the home is usually their most valuable financial asset. The home also symbolizes a sense of independence in that the resident is able to live on his or her own. For these types of reasons, it is understandable that in response to a question about housing preferences, AARP surveys of older persons continue to find that approximately 80% of older persons report that what they want is to "stay in their own homes and never move." This phenomena has been termed the preference to "age in place."Although most older persons move near their current communities, some seek retirement communities in places with warmer weather in the southwest, far west and the south.3. The Federal Government's Housing Programs for the ElderlyThe federal government has had two basic housing strategies to address housing problems of the elderly. One strategy, termed the "supply side" approach, seeks to build new housing complexes such as public housing and Section 202 housing for older persons. Public housing is administered by quasi-governmental local public housing authorities. Section 202 Housing for the elderly and disabled is sponsored by non-profit organizations including religious and non-sectarian organizations. Approximately 1.5 million olderpersons or 3% of the elderly population live in federally assisted housing, with about 387,000 living in Section 202 housing. Over time, the government has shifted away from such new construction programs because of the cost of such housing, the problems that a number of non-elderly housing programs have experienced, and a philosophy that the government should no longer be directly involved with the building of housing. Section 202 housing, a very popular and successful program, is one of the few supply-side programs funded by the federal government, although the budget allocation during the last ten years has allowed for the construction of only about 6,000 units per year compared to a high of almost 20,000 units in the late 1970s. Instead of funding new construction, federal housing initiatives over the last decade have emphasized ‘demand side’ subsidies that provide low-income renters with a certificate or a voucher that they can use in a variety of multiunit settings, including apartments in the private sector that meet rental and condition guidelines. These vouchers and certificates are aimed at reducing excessive housing costs. Some certificates are termed ‘project based’ subsidies and are tied to federally subsidized housing such as Section 202. Because housing programs are not an entitlement, however, supply-side and demand side programs together are only able to meet the needs of about 1/3 of elderly renters who qualify on the basis of income.While advocates for housing have been trying to hold on to the existing programs in the face of huge budget cuts at HUD, much of the attention has been shifting towards meeting the shelter and service needs of the frail elderly. This emphasis reflects the increasing number of older persons in their eightiesand nineties who need a physically supportive environment linked with services. This group of older persons includes a high percentage of older residents of public and Section 202 housing. Initially built for independent older persons who were initially in the late sixties and early seventies, this type of housing now includes older persons in their eighties and nineties, many of whom have aged in place. Consequently, the government is faced with creating strategies to bring services into these buildings and retrofit them to better suit the needs of frail older persons. A major initiative of the early 1990s, which may be stalled by current budget problems at HUD, has been for the federal government to pay for service coordinators to assess the needs of residents of government assisted housing complexes and link them with services. As of 1998, there were approximately 1,000 service coordinators attached to government assisted housing complexes across the country.4. The Housing Continuum: A Range of Options for ElderlyA long-standing assumption in the field of housing has been that as persons become more frail, they will have to move along a housing continuum from one setting to another. As the figure on housing options suggests, along this continuum are found a range of housing options including single family homes, apartments, congregate living, assisted living, and board and care homes (Kendig & Pynoos, 1996). The end point of the housing continuum has been thenursing home. These options vary considerably in terms of their availability, affordability, and ability to meet the needs of very frail older persons.The concept of a continuum of supportive care is based on the assumption that housing options can be differentiated by the amount and types of services offered; the supportiveness of the physical setting in terms of accessibility, features, and design; and the competency level of the persons to whom the housing is targeted. The figure on housing options indicates how such options generally meet the needs of older persons who are categorized,as independent, semi-dependent and dependent. Semi-dependent older persons can be thought of as needing some assistance from other persons with instrumental activities of daily living (IADLs) such as cooking, cleaning, and shopping. In addition to needing assistance with some IADLs, dependent older persons may require assistance with more basic activities such as toileting, eating and bathing. Although semi-dependent and dependent older persons can be found throughout the housing continuum, independent older persons are very unlikely to reside in housing types such as assisted living specifically designed and equipped to meet the needs of frail older persons unless their spouses require these needs.Although the continuum of housing identifies a range of housing types, there is increasing recognition that frail older persons do not necessarily have to move from one setting to another if they need assistance. Semi-dependent or dependent older persons can live in a variety of settings, including their own homes and apartments, if the physical environment is made more supportive, caregivers are available to provide assistance and affordable services areaccessible.5. ConclusionsHousing plays a critical role in the lives of older persons. Most older homeowners who function independently express a high level of satisfaction with their dwelling units. However, high housing costs, especially for renters, remain a financial burden for many older persons and problems associated with housing condition persist especially for low- income renters and persons living in rural areas. Federal housing programs such as public housing, Section 202 housing, and Section 8 housing certificates have only been able to address the basic housing problems of only about one-third of eligible older persons because of limited budgets. Moreover, a shortage of viable residential options exists for frail older persons. Up until the last decade, housing for the elderly was conceived of primarily as shelter. It has become increasingly recognized that frail older persons who needed services and physically supportive features often had to move from their homes or apartments to settings such as board and care or nursing homes to receive assistance. Over time, however, the concept of a variety of housing types that can be linked has replaced the original idea of the continuum of housing. It is possible for frail older persons to live in a variety of existing residential settings, including their own homes and apartments with the addition of services and home modifications. Consequently, the last decade has seen a number of efforts to modify homes, add service coordinators to multi-unit housing and create options such as accessory and ECHO units. Although thesestrategies have been enhanced by a somewhat greater availability of home care services, Medicaid policy still provides incentives to house frail older persons in nursing homes. The most visible development in the field of housing for frail older persons has been the growth of private sector assisted living which is now viewed by many state governments as a residential alternative to nursing homes. The AL movement itself has raised a number of regulatory and financing issues that cross-cut housing and long term care such as what constitutes a residential environment, insuring that residents can age in place, accommodating resident preferences, protecting the rights of individuals and insuring quality of care. Nevertheless, the emergence of AL along with a wider range of other housing options holds out the promise that older persons will have a larger range of choices among living arrangements.译文：老年人的住宅问题与选择一、简介住宅在老年人生活的极为重要。

The base area of the Opera House is the same as the total area covered by four international standard football fields. The building has 1,100 rooms grouped in a number of sections.Front of Opera HouseThe public areas are located in the building`s western section, with access from the area nearby the city`s central train station. These include the main foyer, a large performance auditorium with 1,350 seatsand a small auditorium with 400seats.The large auditorium is designed in `classical` from with a horseshoe type plan and a high ceiling height, providing natural acoustics and good sight lines to the stage. Inaddition to the main stage there is also an under stage complete with elevator, side stages, back stages and a back side stage that can be used as a choir rehearsal room accessible to the public. The small auditorium considerable flexibility, not only for the stage arrangements but also for the seating areas and acoustics. The foyer arrangements but also for the seating areas and acoustics. The foyer is a grand, open room with a variety of lighting conditions and views to the surroundings. This space is characterized by it`s simple use of materials and minimal details. a tall undulating wall formed the separation between foyer and auditoriums. Between reality and fiction. In addition the foyer will contain rest areas, a coatroom, cafe, bars and a restaurant.Rear of Opera HouseThese are the production areas of the building. Here one can findall the workshops, storage areas, rehearsal rooms, changing rooms, offices, and every facility necessary to produce an opera or ballet. Here the building has 4 floors and a basement. The production areas are flexible and robust, able to accept changes over time. The architecture and the use of materials are functionally appropriate, the exteriorfaçade is composed of metal panels.Roof gardenThe roofscape describes the building`s monumental character. The horizontal and sloping plane of the roof provides the opera with an unusually dramatic expression, quite different from the surrounding buildings Its openness and accessibility willallow for a wide range of visitors to traverse its many terraces. The roofscape will be open to the public, it`s clad in white stone, and it`s details will provide a holistic and symbolic character to the building while also allowing for a variety of experiences as one moves past it.Valencia Opera HouseSantiago Calatrava S.A. / Santiago CalatravaThe people of Valencia have traditionally shared a deep love of music. The region is sometimes known as the `Land of 1,000 Bands` since every village and town has its musical association. In fact Volencia, called the `City of Music`, has two, which are respected throughout the world. The project of creating the Valencia Opera House is therefore highly significant-because of the role that music plays in the life of the region, and because of the role that the building plays in the physical evolution of the city.The Valencia Opera House was the first major element in the City of Arts and Sciences, and when it is completed, in 2006, it will be the last. It was the first, because my involvement with this great development began in 1991, when I won a competition to design astructure where the Opera House now stands. It will be the last, becausethe original commission was not for a cultural building but for a telecommunications tower. It was in 1996 that the Valencian government altered the programfor the City of Arts and Sciences. That was when a magical transformation took place on the original site, as the planned telecommunications towe was changed into a proposed opera house.So the plan for the entire sequence of buildings, strung from westto east along the dry bed of the Turia River, began from this one site and has returned to it. The Planetrarium / IMAX Therater (Hemispheric Theater) was completed in 1996 ; the Principe Felipe Science Museum in 2000. Now, in 2006, we come back to the westernmost part of the project area, to celebrate the first concert in the Valencia Opera House.Looking back, I feel as if the deeper meaning of the Valencia Opera House may be bound up with this project history, with its themes of trans-formation and recurrence. As a grand urban intervention, intened to link two areas that had been separated geographically, socially and economically, the City of Arts and Sciences both changes Valencia and returns it to a condition of wholeness. The means we have used -engineering and construction- have been technical, as symbolized perhaps by the telecommunications tower. But the place at which we arrive is artisitic : the Opera House.As a native of Valencia, who was formed by this city and who is attached to it deeply, I feel both proud and humble to have played arole in this process of change and reunion. It is very moving to me that this story should culminate as it does, not with a burst of microwavesbeing emitted from a tower, but with our citizens gathering together in a new puclic space, to be surrounded with the music they love.汉语译文奥斯陆歌剧院,斯诺赫塔事务所 / 谢蒂尔.索森, 克雷格戴克斯奥斯陆歌剧院,这是挪威的最大的文化建筑,是作为挪威国家的现代化的一个重要标志和代表,展现了歌剧和芭蕾舞对社会的作用。

本科生毕业设计外文资料翻译专业建筑学班级092班姓名XXX指导教师XXX所在学院XXX附件 1.外文资料翻译译文；2.外文原文学校建筑规划设计漫谈在校园内的功能和各种需求亦趋向于多元化，在规划、设计中必须要找出一种合适的方法来适应、符合现在及未来的世界潮流需要。
1、学校的功能和秩序学校特别是高等学校的功能相对来说是比较复杂的，在规划设计中要充分考虑到学校中的功能分区和教学的秩序，才能做到有合理的设计和良好的规划。
教学区是校园的核心，是校园建设中的最关键的部分。
学校中的一切其它功能均是围绕其进行的。
教学区的布局主要有组团式与网络式两种主要设计方法。
组团式便于院系相对独立地组织教学活动与进行管理，更能适应建校周期较长而分期施工的现实。
“院落”是是中国传统的建筑布局形式，由建筑所围成的庭院形成社交性的公共空间，也有利于学校中的交流。
网络式的发展规划有利于不同的科系在今后的发展中专业更新与规模调整，并可灵活调节教学用房的使用性质，因此被现代的新型校园规划布局所偏爱，它利于目前国内的大学院校、院系合并和学科调整的教学改革大趋势。
学生宿舍生活区是大学校园内又一个重要的组成部分，无论改革后学生生活区社会化管理落实的力度有多大，还是由于扩招形式的“不是数着床板招生”的局面到何种程度，在目前的实际情况下，新建的大学校园仍然需要规划好学生生活区的建设。
当然要充分考虑到如何便于社会化的管理，有利于形成独立的管理系统，为以后的发展留有可能性。
2、学校的交通组织高等学校交通组织中，首要的是要体现以人为本的思想。
根据教师、学生的心理及行为方式研究各种道路组织、形态和层次，创造一个满足校园使用者的物质和精神上要求的校园环境。
现代校园要求建筑物之间能联络方便、尽量通畅、便捷。
为此，各类建筑物的设计，多采用集中式的布局，建筑群体也多以成团的方式组合，尽量减少楼间的距离几交通路线。
各个相对独立的区域之间，也尽量打通分割界限，室内外都设有方便的连廊和通道，使建筑群体在整体上能联络通畅，达到提高和保证交通、交流、传递、沟通之最佳的效率。

译文标题东西方的会合原文标题WEST MEETS WAET作者MIES VAN DER ROHE 译名密斯·凡·德·罗国籍德国原文出处密斯·凡·德·罗导读系列日本人安藤忠雄的建筑是当代建筑神话的绝佳范例。
他的建筑和平而静谧：它们是敏感的，同时又保持着朴素的、自然的要素。
然而，恰恰又是这朴素给虚空之美赋予了生命。
只有借助超乎寻常的专注，以及与古典主义密切相联的深思熟虑的专业训练，才能创造出这样的虚空之美。
“材料、结构与设计”是一条引人实现上述美学含义的途径——在心有灵犀的宁静气氛中，这种美学含义仿佛是卓有成效，然而又出乎意料的呼唤，使得无论建筑的使用这还是旁观者，都会稍作停留并发现内在的和平，进而被吸引到世界的本质的和谐当中。
感觉自己是宇宙的一部分，是开敞空间与自由的一部分，这种东方建筑的显著特色，已经深深地融入了现代主义的核心。
关注人类思想和行为的东方文化引导我们进入冥想世界。
日本的禅宗不仅以强调朴素和自然而闻名，还以专注于沉思和日常生活的感受而著称。
有充分的理由表明，在安藤忠雄的建筑方案中蕴含的创造激情同样源于类似的精神观，并表露出一种非比寻常的敏感。
我们在密斯的作品中已经遇到了这种现象。
凭借这样的精神观，建筑就能触及到人性的根本——全部人性——并创造出一种超凡脱俗的高贵和美丽的感觉。
对于短暂的、难以存在的方式，安藤忠雄的基本观点同样与东方的思想保持一致，就如他寻觅一种几乎是抽象的，或者说至少是解放的然而又是动态的设计一般。
不过不管建筑的组织方式再怎么变化或开放，他创造的空间所特有的形式上的和美学上的协调，都反反复复提醒我们那句禅宗格言：“万物生一，一生万物”。
亭的意义无言的建筑——“无”中生“有”亭——即现代拉丁语中“papilio”，意为愉悦的帐篷——是独立的建筑物，它朝多个方向敞开，并成为约定俗成的与自然景观或园林相关的事物。
植被，蜿蜒的流水以及与之相称的围墙，是来自周围环境的美学要素，它们更衬托出亭的美。

Providepeople with healthy, appropriate and efficient use of space, and nature in harmony symbiosisbuildings. I described more details of green building design’ notion, green building’ design, as well as the significance of the concept of green building and improve the effectiveness analysis of the external effects of green building measures, Key words: green buildings; protect the ecology; signification ; analysing the effects1 What is a green buildingGreen building refers to building life cycle, the maximum conservation of resources (energy, land, water and materials),protecting the environment and reduce pollution, provide people with health, application and efficient use of space, and nature harmony of the building. The so-called green building "green" does not mean a general sense of three-dimensional green, roof garden, but represents a concept or symbol, refers to building environmentally friendly, makefull use of natural resources, environment and basic ecological damage to the environment without balance of a building under construction, but also known as sustainable building, eco-building, back into the wild construction, energy saving construction.Green building interior layout is very reasonable, to minimize the use of synthetic materials, full use of the sun, saving energy for the residents Chuangzao almost-natural feeling.People, architecture and the natural environment for the harmonious development goals, in the use of natural and artificial means to create good conditions and healthy living environment, as much as possible tocontrol and reduce the use and destruction of the natural environment,to fully reflect the nature obtain and return balance.2, the meaning of green buildingThe basic connotation of green building can be summarized as: to reduce the load on the environment architecture, which save energy and resources; provide a safe, healthy, comfortable living space with good; affinity with the natural environment, so that people and building a harmonious coexistence with the environment and sustainable development.3 Development of the significance of green building rating systemEstablish green building rating system is a revolution in the fieldof architecture and the Enlightenment, its far more than energy savings.It is innovative in many ways and organic synthesis, thereby building in harmony with nature, full utilization of resources and energy, create healthy, comfortable and beautiful living space. It's revolutionary for the field of architecture from the technical, social and economic angles.3.1 Technical SignificanceGreen building study of early technical problems of individual-based, technology is isolated and one-sided, not formed an organic whole, the integration of design and economic study of consciousness is far fromthe only strategy of economic analysis phase of the subsidiary's knowledge . However, individual technical research results of early modern green building techniques for the multi-dimensional developmentand systems integration will lay a solid foundation. Since the ninetiesof the 20th century, with the understanding of green building graduallydeepen and mature, people give up way too utopian thinking He alone environmental consciousness and moral constraints and spontaneous green behavior, turned to explore more workable environmental philosophy, environmental and capital combined into the future world the newdirection of development of environmental protection, green building has entered a result of ecological ethics from the practice of promoting ecological research to deepen the new stage. Green Building Technology takes on the natural sciences, social sciences, humanities, computer science, information science and other subjects the trend of integration of research results, making green building design into the multi-dimensional stage of development strategy study. The deepening of green building technology strategy anddevelopment in materials, equipment, morphology, etc variousadvanced fields, in technology development, technology and other design elements of the integration is also starting from the past the simple addition, more attention to the periphery of the retaining structureitself design technology and architecture to combine the overall system change, gradually becoming green building systems. Green building rating system was established green building technologies gradually improve and systematize the inevitable result, it is the organic integration ofgreen building technology, a platform built to green building technology, information technology, computer technology and many other subjects can be a unified platform in their respective roles, the establishment of a comprehensive evaluation system for designers, planners, engineers andmanagers a more than ever, a more simple, Guizhangmingque green building assessment tools and design guidelines.3.2 The social significance.Green building rating system reflects the social significance of the main advocates of the new way of life, heightened awareness and public participation in the continuation of local culture are two aspects.To promote a healthy lifestyle. Green building rating system, the social significance of the primary advocate a healthy lifestyle, whichis based on the design and construction of green buildings as a community education process. The principles of green building rating system is the effective use of resources and ecological rules to follow, based on the health of building space to create and maintain sustainable development. The concept of the past to correct people's misconceptions about consumer lifestyles, that can not blindly pursue material luxury, but should keep the environment under the premise of sustainable use of modest comfort to pursue life. From the fundamental terms, construction is to meet human needs built up of material goods as people's Wenhuayishi Name and lifestyle is not sustainable when, the value of green building itself will be reduced, but only had a real social need When the requirements of sustainable development and way of life that matches the green building to achieve the best results.Enhanced awareness of public participation. Green Building Rating system is not a monopoly for the design staff of professional tools, but for planners, designers, engineers, managers, developers, propertyowners, jointly owned by the public and other assessment tools. It broke the previous professional development of the monopoly to encourage the participation of the public and other public officers. Through public participation, the introduction of architects and other building users, the construction of dialogue participants, making the original design process dominated by the architect becomes more open. Proved the involvement of various views and a good help to create a dynamic culture, embody social justice community.3.3 The economic significance.Green building rating system, the economic significance can bedivided into macro and micro levels. At the macro level, the green building rating system from the system life-cycle perspective, the green building design integrated into the economic issues involved in the production from the building materials, design, construction, operation, resource use, waste disposal, recycling of demolition until the natural resources the whole process. Economic considerations of green buildingis no longer limited to the design process itself, while the policy extended to the design of the narrow role to play to support the policy level, including the establishment of "green labeling" system, improving the construction environmental audit and management system, increase and construction-related energy consumption, pollutant emissions and other acts of tax efforts, improve the legal system of environmental protection, from the increase in government construction projects on the sustainability of economic support and raise the cost tothe construction of polluting the environment acts as the costs for green buildings design and construction to create a favorable external environment. This goal is not entirely the responsibility of government agencies, as the architects involved in design work as a sound system of responsibility for recommendations obligations, because only the most from the practice of the need is real and urgent. The related policy issues in green building design strategies, building a system to solve the economic problems facing the important aspects. At the micro level, the current from the economic point of Design Strategy is more fully consider the economic operation of the project, and specific technical strategies accordingly adjusted.3.4 Ethical Significance.Green building rating system, the theoretical basis of the conceptof sustainable development, therefore, whether the evaluation system of each country how much difference in structure, they all have one thingin common: reduce the burden of ecological environment, improve construction quality of the environment for future generations to remain the development of there is room. This radically change the long-sought human blindly to the natural attitude, reflecting people's understanding of the relationship between man and nature by the opposition to the uniform change. According to the current global energy reserves and resources distribution, the Earth's natural environment is also far from the edge of exhaustion, enough people enjoy the luxury of contemporary material life. But now we have to consume a resource, it means thatfuture generations will be less of a living space. More importantly, if we consume the natural environment more than it can limit self-renewal, then the future of the younger generation is facing the planet's ecosystems can not recover the risk into a real crisis. Therefore we can say, the development of green buildings and their corresponding evaluation system, for more contemporary people is the responsibility and obligations. For more the interests of future generations and advantages. 4 green building designGreen building design include the following:Saving energy: full use of solar energy, using energy-efficient building envelope and heating and air conditioning, reducing heating and air conditioning use. Set according to the principle of natural ventilation cooling system that allows efficient use of building to the dominant wind direction in summer. Adapted to local climatic conditions, building use form and general layout of the plane.Resource conservation: in the building design, construction and selection of construction materials, are considered fair use and disposal of resources. To reduce the use of resources, strive to make the use of renewable resources. Conserve water resources, including water conservation and greening.Return to Nature: Green Building exterior to emphasize integration with the surrounding environment, harmony, movement complement each other so that the protection of natural ecological environment.5 Effect of green building5.1 Effect of the composition of green buildingEffect of green building, including internal effects and external effects, direct benefits and direct costs as the internal effect, known as the indirect benefits and indirect costs of external effects, according to engineering economics point of view: the internal effects can be financial evaluation, external effects should be economic evaluation, economic evaluation is based on the so-called rational allocation of scarce resources and socio-economic principles of sustainable development, from the perspective of the overall national economy, study projects spending of social resources and contributions to the community to evaluate the project's economic and reasonable and external effects generally include Industry Effects, environmental and ecological effects, technology diffusion effect, the external effectwill cause the private costs (internal costs or indirect costs) and social costs inconsistent, leading to the actual price is different from the best price. From the perspective of sustainable development, green building assessment effects of the main indicators of external effects. Since beginning the development of green building, unity of quantitative indicators system is still not established, I believe that the following aspects should be analyzed: (1) strictly control the construction industry, size, limit the number of employees. Extensive growth model epitomized by the struggle over the construction project, the construction process using human wave tactics, once the state limit the scale of construction, will form the "adequate", which will not reducethe degree of mechanization, labor, the low level. (2) more investments in technology, upgrade technology, establish and perfect the mechanism for scientific and technical equipment. Focus on the development and application of building technology, combined with the project, the characteristics of future construction, a planned way scientific and technological research and development of new machinery, new processes, new materials, and actively introduce, absorb and assimilate the advanced scientific and technological achievements of science and technology to improve the level of mechanization. (3) in urban planning, survey and design through the "green building" ideas. Family housing and urban construction or alteration must remain in the room, from lighting, ventilation, drainage and so control the damage to the environment. (4) construction work, reduced resource consumption, the production process in construction, energy saving measures should be adopted to prevent the excessive consumption of land resources, water resources, power resources.5.2 External effects of the challenges to building the economyUnder the control of the government's intervention, to a certain extent on the efficient allocation of resources to strengthen the implementation of energy conservation mandatory standards for construction supervision. To further improve the building energy monitoring system, and strengthen the mandatory building energy efficiency standards in order to carry out the implementation of the project as the main content of the whole process of monitoring,particularly for large public buildings to enhance the building energy regulation, reflected in the project cost on the part of the Waibu costs into internal costs, making the "non-green building" project's internal costs, internal efficiency and reduce the external costs of green building, the external efficiency increase, so that effective economic resources to the rational flow of greenbuilding.6 to improve the external effects of green building measuresEnterprise architecture in the new economy to obtain a competitive advantage, improve the external effects only continually tap the ways and means to improve the external efficiency, reduce external costs, the basic ideas and principles: (1) Construction of natural resources in the life cycle and minimize energy consumption; (2) reducing building life cycle emissions; (3) protect the ecological (natural) environment; (4) to form a healthy, comfortable and safe indoor space; (5) the quality of construction, functionality, performance and environmental unity.Summarydescribed above, the meaning of green building design and analysisof its effectiveness and improve the external effects of green building measures. But how does the future design of green buildings need a degree in practice we try to figure out, I believe that green building will become the future construction of a trend.译文:博士生论坛国家期刊出版和指导博士生研究第7卷，第1号，2010绿色建筑Priscilla D.
