Cables transmit the loads to the towers and foundations
The Application of Suspension Bridge
When the spans are about 600m or more, suspension bridges are the most economical, but they can, of course, be used for smaller spans.
Introduction of SUSPENSION Bridges
Lecturer: Student ID:1512
Definition
A suspension bridge(悬索桥) is a type of bridge in which the deck is hung below suspension cables on vertical suspenders（吊杆）. This type of bridge dates from the early 19th century. This type of bridge has cables suspended between towers, plus vertical suspender cables that carry the weight of the deck below, upon which traffic crosses.
Main Components
Cables are fixed on the towers decking Cable anchorage Suspenders carry the load of decking and cars by tension and transmit the force to cables.
Humber bridge(1410m)
Nanjing Yangtze river no.4 bridge (1418m)
Golden Gate Bridge(1280m) Zhoushan xihoumen bay bridge(1650m)
Background
It was constructed as a 1660 metre long suspension bridge with a mainspan of 853 metres , the third longest suspension bridge in the world at that time. The bridge deck was 11.9 metre wide, supported by two 2.45 metre deep plate girders (I-girders).

New Tacoma Narrows Bridge
Thank you for your attention!
Why did it collapse?
A graceful bridge with the lightest wave was designed to make the bridge look more eleuction cost. The bridge used shallow plate girders that decreased the weight, which ended up making the bridge less stable. Another problem was that the bridge was too long for it’s width.
伦敦塔桥介绍简介
伦敦塔桥介绍简介
伦敦塔桥（Tower Bridge），是一座上开悬索桥，位于英国伦敦，横跨泰晤士河，因在伦敦塔（Tower of London）附近而得名，是从泰晤士河口算起的第一座桥（泰晤士河上共建桥15座），也是伦敦的象征。
该桥始建于1886年，1894年6月30日对公众开放，将伦敦南北区连接成整体。
在19世纪下半叶，随着伦敦东区商业的上升发展，带动了对伦敦桥下游一座穿过泰晤士河的新桥梁的需求。
但这座桥不能建成是传统的固定桥，因为将会切断当时位于伦敦桥和伦敦塔之间的港口设施，假如新桥太低的话船就无法开到码头了。

写桥梁的英文作文
写桥梁的英文作文英文：When it comes to bridges, I believe they are one of the most fascinating structures in the world. Bridges connect people, places, and cultures, and they have been doing so for centuries. As an engineer, I have always been fascinated by the design and construction of bridges. There are so many different types of bridges, each with its own unique features and challenges.One of my favorite types of bridges is the suspension bridge. These bridges are held up by cables that are anchored to towers on either side of the bridge. The cables are then attached to the bridge deck, which is suspended above the water or the ground. Suspension bridges are often used to span large distances, such as across a river or a bay.Another type of bridge that I find interesting is thearch bridge. These bridges are supported by arches that are built into the structure of the bridge. The weight of the bridge is transferred to the arches, which then transfer the weight to the ground. Arch bridges are often used for shorter spans and are known for their strength and durability.In addition to their functional purposes, bridges can also be works of art. Many bridges around the world are famous for their beauty and design. For example, the Golden Gate Bridge in San Francisco is not only an engineering marvel, but it is also a symbol of the city and an iconic image recognized around the world.Overall, I believe that bridges are an essential part of our infrastructure and our culture. They connect us to each other and to the world around us, and they are a testament to human ingenuity and creativity.中文：谈到桥梁，我相信它们是世界上最迷人的结构之一。

2 Description and modeling of the bridgeBeing a type of multi-tower suspension bridge, the TaizhouYangtze River Bridge is longest in the world with the dualmain spans reaching 1080m. As shown in Fig.1, the bridgeconsists of three towers, making two main spans (1080m) andtwo side spans (390m). The sag-span ratio of cable is 1/10, andthe transverse spacing between the two main cables is 35.6m.The streamlined steel box girder is 3.6m high and 36.9m wide.Of the three towers, two side-towers are made of concrete witha height of 178m. The tower located in the middle is 192m inheight and constructed with steel. All the towers are doorshapedin the transverse direction. But in the elevation view,the middle tower differs from the two side-towers with aninverted Y-type.Fig. 1. Taizhou Yangtze River BridgeThe computer program SAP2000 is used to establish a 3Dfinite element analytical model of the bridge. The steel girder,as well as the towers, is idealized as 3D beam elements, and thehangers and the cables are modeled using 3D bar elements. Inconsidering the nonlinear behaviors, effects of axial forceunder dead load on structural components’ geometricalstiffness are incorporated in the model. The girder is connectedby an elastic spring to the mid-tower but remains relatively freeat the side-towers in the longitudinal direction. In thetransverse direction, however, the girder is constrained to all the three towers. The 3D finite element analytical model ofTaizhou Yangtze River Bridge is shown in2/of the bridge site is carried outby Jiangsu Earthquake Bureau. According to the analysis, theseismic fortification intensity of the bridge site is assessed tobe 7 degree and the peak ground acceleration is 1.65m/s2：地震设防烈度为7度Fig.3presents one of these three pieces of horizontal groundaccelerations.3/4.1 Seismic demands on structure componentsFor Taizhou Yangtze River Bridge, a multi-tower suspensionbridge with large spans, nonlinear time history analysis methodcould be most proper in determining the seismic demand forthe bridge structure.This study presents an analytical methodology fordeveloping seismic fragility assessments for a long-span multi-towersuspension bridge, i.e. Taizhou Yangtze River Bridge.Based on the results of this comprehensive analytical study, thefollowing main conclusions can be made.For Taizhou Yangtze River Bridge, the smallestC/D ratio values are found to be at the bottom of the tower, ataround 1/4 height of the tower-column from the top of thetower, at some places of the pile foundations and at the saddleswhere the slip of the main cables may happen under the Ex+E zearthquake input：地震输入DESCRIPTION OF THE BRIDGEA bridge has been approved to build by the government of Xi’ning City, Qinghai Province to connect the two sides of Huangshuihe River. As an important project of Xi’ning city, the project owners determined to build a self-anchored suspension bridge for aesthetic considerations. The bridge is a two-tower self-anchored suspension bridge with a span layout of 24m+65m + 158m+65m + 24 m, Figure 1 shows the architectural effect figure of the bridge.The sag of the main cable is 26.333m and the span:sag ration is 6:1. The main girder is a concrete box girder with a height of 2.2m and a width of 27.3m.There are 41 couples of vertical hangers with 25supporting the main span and 8 supporting each side spans. The hangers are evenlyspaced with a distance of 6m at the deck level on the side as well as main spans The two towers have same height of 45.4m from the top of their pile capsA three-dimensional model (Figure 2, Figure 3) of the bridge was built inSAP2000 to perform the dynamic analysis. The coordinates system of the model was set as x-axis along the longitudinal direction of the bridge, y-axis along the transverse direction and z-axis in the vertical direction. Frame type elements have been used to model the girder, towers, piers, piles, main cables and hangers. Bearings and dampers were modeled with link type elements.Compression limit was set as zero for the main cables and hangers：主缆和吊杆不能压缩Seismic excitations were exerted on the bridge model in horizontal and vertical directions simultaneously during the analysis process.For loading cases of time history analysis (THA), Rayleigh damping was used to model the damping of the bridge. To calculate the proportional coefficients of global mass and stiffness matrix, 5% was chosen as the damping ratio of two dominant vibration modes which contributed most modal participating mass in the considered direction of earthquake input.DYNAMIC CHARACTERISTICS OF THE BRIDGEThe boundary conditions of the deck were assumed as type A in Table 1. In orderto have a good understanding of the modal characteristics of the bridge, the modal analysis was performed on the bridge model and the first 10 vibration modes of which are listed in Table 2. As no constraints were applied in the longitudinal direction of the deck, the long-period longitudinal drift mode of the deck becomes the first mode.CONCLUSIONSBy studying the seismic performance and design optimization of theself-anchored suspension bridge, the following conclusions can be draw。
悬索桥(xuán suǒ qiáo)Suspension Bridge—中国古建筑及其故事英文版介绍
悬索桥(xuán suǒqiáo)Suspension BridgeProviding a connection through history Ancient Chinese began building suspension bridges more than 2,500 years ago. At first theyused wicker, bamboo or yak skins to build such structures to sling across chasms in mountainousareas.Few historical records can be found about such structures and the building materials have longsince decayed.Luding Bridge in Sichuan Province is one of the traditional suspension bridges, which were not as popular asbeam bridges or arch bridges in central and eastern China, butwidely built in the mountainous area ofwestern China. However, there are records of a bamboo suspension bridge built in the third century BC by LiBing (302–235 BC), a famous engineer. Located near today's Chengdu, capital of SichuanProvince. It is said this bamboo bridge was in use for more than 600 years.Iron chain suspension bridges first appeared in China during the T ang Dynasty (618–907 AD), butsuch bridges still in existence today were mostly built during the Ming Dynasty (1368–1644).In 1430, Thangtong Gyalpo (1385–1464), a great Tibetan Buddhist, architect and creator ofTibetan opera, built an iron chain bridge spanning the Yarlung Tsangpo River south of Lhasa,capital of the Tibetan Autonomous Region today. Boasting a central span of 137 meters, it was the suspension bridge with the longestunsupported span in the world at that time. The bridge's wooden plank walkway hung fromvertical poles and the planks were bound together with twisted willow and strips of yak hide.According to legends, Gyalpo, known as the "Buddha of Iron Bridges" at his time, built a total of58 iron chain suspensionbridges in his whole lifetime.The structure of Tibetan architect Thangtong Gyalpo's iron chain bridge on the Yarlung Tsangpo RiverAnother ancient iron chain suspension bridge with detailed historical records in China was theJihong Bridge, spanning the Lancang River in southwest China's Yunnan Province.It was once called the "First Bridge in Southwest China" as it sat on an ancient path leading toIndia and Myanmar.The iron chain link bridge was built in 1475, replacing a bamboo structure.With a total length of 113.4 meters and a width of 3.7 meters, the bridge was built with 18 thickiron chains and featured a span of 57.3 meters.However, the ancient bridge was washed away by floods in 1986.Another masterpiece of historic suspension bridges is the Luding Bridge. Built in 1706 in thesouthwest China's Sichuan Province, the 103-meter-long and 3-meter-wide bridge is made from13 thick iron chains with a total weight of more than 40 tons.The bridge was long regarded as a key link in connecting Sichuan Province and the Tibetanregion. But it is today also known for a fierce battle fought there by the Chinese CommunistParty-led Red Army in May 1935 against Kuomintang allied local warlords during its famous LongMarch to reach its bases in northern China.In 1961, the bridge was listed among the first batch of key cultural relics of the country and putunder state protection. Today it is a popular tourist attraction drawing throngs of visitors everyday.Though suspension bridges were not as popular as beam bridges or arch bridges in ancientChina, in the past several decades, the country has built many world-class suspension bridges tomeet its needs for modernization.The Xihoumen Bridge was built in 2009 on the Zhoushan Archipelago in east China's Zhejiang Province, witha main span of 1,650 meters.They include the Xihoumen Bridge built in 2009 on the Zhoushan Archipelago in east China'sZhejiang Province, with a main span of 1,650 meters; the Runyang Yangtze River Bridge built in2005 in east China's Jiangsu Province, with a main span of 1,490 meters; the Fourth NanjingYangtze Bridge build in 2012 also in Jiangsu Province, with a main span of 1,418 meters; and theJiangyin Yangtze River Bridge built in 1999 also in Jiangsu Province, with a main span of 1,385meters.All the four above are among the top 10 suspension bridges in the world today in terms of the length of their main spans.Pictorial dictionary·吊桥(diào qiáo) drawbridgeIn Chinese, the term diaoqiao may mean either a suspension bridge or a drawbridge. Asuspension bridge can also be called xuansuoqiao in Chinese, but the drawbridge doesn't haveanother common alias.Also, unlike in other parts of the world, where the term drawbridge may refer to a number ofmovable bridges, such as bascule bridge, vertical-lift bridge and swing bridge, in ancient China adrawbridge was used almost exclusively of the bridge installed in front of a city wall gate andspanning a surroundingmoat.Such city moat drawbridges were mostly made of wood and could be raised —particularly toprevent invading troops from entering the city.Many Chinese historians and architects believe that the first drawbridges appeared in Chinaduring the Spring and Autumn Period (770–476 BC), together with the city moat.。
