梁、柱最大最小配筋率
最小配筋率计算方法

最小配筋率计算方法在结构工程设计中,配筋率是指钢筋与混凝土截面积之比。
为了确保混凝土结构的受力性能和安全性,工程师需要根据设计要求计算出最小配筋率。
本文将介绍最小配筋率的计算方法和应用。
最小配筋率的定义最小配筋率是指混凝土截面所需的最小钢筋面积与混凝土截面面积之比,通常用百分比表示。
最小配筋率的计算有助于确保结构的强度和耐久性,以及预防混凝土的开裂和破坏。
最小配筋率的计算方法最小配筋率的计算依赖于结构的类型和设计要求。
一般情况下,可以使用以下两种常见的计算方法:1. 经验法经验法是一种简化的计算方法,一般用于简单结构的设计。
常见的经验法包括:- 根据结构的用途和设计要求,选择适当的配筋率范围。
例如,室内墙体的最小配筋率一般为0.15%到0.25%,梁和柱的最小配筋率一般为0.5%到1%。
- 根据结构的受力情况和设计要求,选择适当的配筋率值。
常见的做法是根据已有的设计经验和结构的使用要求来确定配筋率。
2. 法规法法规法是一种更为严谨的计算方法,通常用于复杂结构的设计。
不同地区和国家的法规法可能有所不同,但一般包括以下步骤:- 根据结构的类型和用途,查阅相应的建筑设计规范和法规。
例如,在中国,可以参考《混凝土结构设计规范》(GB 50010-2010)中的相关规定。
- 根据规范中给出的计算公式和要求,计算出最小配筋率的数值。
这通常涉及到混凝土强度等材料参数、结构受力情况和安全要求等因素。
- 验证所得的配筋率是否满足设计要求。
如果计算得到的配筋率小于最小配筋率,需要调整设计方案,增加钢筋数量或改变结构形式,以确保结构的安全性。
最小配筋率的应用最小配筋率的计算结果可以对结构的设计和施工起到重要的指导作用。
具体应用包括:1. 结构设计:根据计算得到的最小配筋率,工程师可以确定结构中所需的钢筋数量和布置方式,以满足受力和安全要求。
2. 施工控制:施工过程中,可以根据最小配筋率的数值进行验收和控制,确保钢筋的正确数量和布置位置,避免结构的缺陷和质量问题。
纵向受力钢筋的最小配筋率

纵向受力钢筋的最小配筋率1. 什么是最小配筋率?大家好,今天我们来聊聊一个在建筑圈里经常提到的概念——最小配筋率。
说到这个,很多人可能会觉得这是个很高深的技术名词,其实说白了,就是我们在建房子的时候,钢筋用得够不够。
想象一下,建房就像做一道美食,配料的比例可不能马虎,少了或者多了都会出问题。
最小配筋率就是告诉我们,钢筋这道“配料”得按规定来,不能随便忽略。
否则,就可能出现“过火”或者“味道淡”的情况,那可就麻烦了。
1.1 为什么需要最小配筋率?说到这里,可能有人会问,为什么非得有个最小配筋率呢?这可不是多此一举,大家想想,房子可不是纸糊的,受力、抗震、承重这些问题都关系到我们居住的安全。
就好比你在走路,脚下的地面如果不够结实,摔了一跤那可真是“倒霉透顶”。
钢筋就像是房子的“骨头”,最小配筋率则是确保这些“骨头”足够强壮的标准。
所以,确保最小配筋率,不仅是为了让建筑物更牢固,也是为了保护我们自己的安全。
1.2 最小配筋率的计算那么,如何来计算这个最小配筋率呢?这里面其实有点“门道”。
通常情况下,我们会根据混凝土的强度等级、构件的类型等因素来决定。
在实际操作中,最小配筋率一般用百分比来表示,这就像我们做菜时,需要根据食材的特性来调整调料的用量。
比如,对于普通的钢筋混凝土梁,最小配筋率一般会在0.2%到0.3%之间。
听起来可能不算多,但这就像是你的面条里加点盐,少了味道可就差多了。
2. 最小配筋率的影响因素接下来,我们再聊聊影响最小配筋率的几个因素。
首先,构件的类型。
不同的构件需要的配筋率是不一样的,就像人各有各的喜好,面食爱好者和甜品控的需求可完全不同。
其次,混凝土的强度也会影响配筋率,强度越高,可能所需的配筋率就越低。
再者,受力情况也是一个关键因素,承受的载荷越大,自然需要的钢筋也就越多。
2.1 构件类型对于梁、柱、板等构件,它们的受力状态各有不同,所需的钢筋配比自然也就不同了。
比如说,梁的受弯比较明显,而柱则主要受压,所以它们的最小配筋率就得根据具体情况来调整,就像在做不同风味的菜肴,总得有个主料和辅料的搭配嘛。
梁配筋计算

配筋率:配筋率是钢筋混凝土构件中纵向受力(拉或压)钢筋的面积与构件的有效面积之比。
柱子为轴心受压构件。
在桥梁工程中,一般指的是面积配筋率,即受拉钢筋面积与主梁面积之比。
基本含义:配筋率是钢筋混凝土构件中纵向受力(拉或压)钢筋的面积与构件的有效面积之比(轴心受压构件为全截面的面积)。
受拉钢筋配筋率、受压钢筋配筋率分别计算。
钢筋混凝土构件最小配筋率如下:受压构件:全部纵向钢筋0.6%;一侧纵向钢筋0.2%受弯构件、偏心受拉、轴心受拉构件一侧的受拉钢筋0.2%计算公式:1.ρ=A(s)/A。
此处括号内实为角标,,下同。
式中:A(s)为受拉或受压区纵向钢筋的截面面积;A根据受力性质不同而含义不同,分别为:1. 受压构件的全部纵筋和一侧纵向钢筋以及轴心受拉构件、小偏心受拉构件一侧受拉钢筋的配筋率计算中,A取构件的全截面面积;2. 受弯构件、大偏心受拉构件一侧受拉钢筋的配筋率计算中,A 取构件的全截面面积扣除受压翼缘面积(b'(f)-b)h'f后的截面面积。
最小配筋率是指,当梁的配筋率ρ很小,梁拉区开裂后,钢筋应力趋近于屈服强度,这时的配筋率称为最小配筋率ρ(min)。
最小配筋率是根据构件截面的极限抗弯承载力M(u)与使混凝土构件受拉区正好开裂的弯矩M(cr)相等的原则确定。
最小配筋率取0.2%和0.45f(t)/f(y)二者中的较大值!最大配筋率ρ (max)=ξ(b)f(c)/f(y),结构设计的时候要满足最大配筋率的要求,当构件配筋超过最大配筋率时塑性变小,不利于抗震。
配筋率是影响构件受力特征的一个参数,控制配筋率可以控制结构构件的破坏形态,不发生超筋破坏和少筋破坏,配筋率又是反映经济效果的主要指标。
控制最小配筋率是防止构件发生少筋破坏,少筋破坏是脆性破坏,设计时应当避免。
2.箍筋面积配筋率:面积配筋率(ρsv):配置在同一截面(b×s,b为矩形截面构件宽度,s为箍筋间距)内箍筋各肢的全部截面面积与该截面面积的的比率。
混凝土各构件的配筋率及构造要求

1.配筋率:
配筋率是影响构件受力特征的一个参数,控制配筋率可以控制结构构件的破坏形态,不发生超筋破坏和少筋破坏,配筋率又是反映经济效果的主要指标。
控制最小配筋率是防止构件发生少筋破坏,少筋破坏是脆性破坏,设计时应当避免。
2.计算公式:
①配筋率ρ=As/bho
②最小配筋率ρmin=As/bho
③公式说明ho-有效高度ho=h-as(保护层厚度)
④板的配筋面积 As=配筋率×板厚×1米板长(1000)得出构造配筋(板厚应减去保护层厚度)
3.框架梁配筋率及配筋要求:
通常配筋率:跨中1%~1.7%,支座1.5%~2%;
4.板:
通常配筋率0.4%~0.8%
5.柱:
通常配筋率1%~3%;
柱主要是受压构件,一般来说,计算引起的配筋不要超过最小配筋率太多。
还有要注意柱的大偏心,小偏心情况,和抗震等级高时角柱配筋。
一般来说,柱必须满足最小轴压比要求,当然是越小越经济。

关于最小配筋率最大配筋率(试题学习)
关于最小配筋率最大配筋率关于最小配筋率最大配筋率与梁高的取值第一是最小配筋率,最小配筋率的确定理论原则应该是受弯构件的第一阶段末,即截面受拉区砼开裂临界状态,此时的配筋应能承担砼开裂后转嫁的全部拉应力,故与全截面有关,应用全截面。
第二是正常的配筋率或最大配筋率,针对的是受弯构件第三阶段,即极限破坏状态,此时截面只与有效高度有关,保护层多厚都无用,故采用有效高度。
______配筋率首先要满足砼本身的要求,(参见大家上学时的混凝土教材正截面受压计算)。
混凝土受压区高度不能无限增大,太大时会在钢筋屈服前压溃,超筋破坏。
所以教材上是控制ξb(常用材料在0.5附近),所以我们的受拉钢筋配筋梁受ξb不能超过一定值,这个值随着截面尺寸砼等级钢筋等级保护层厚度的不同,值也不同。
我通过列表计算得出的结论是:对于常用材料和截面,梁的配筋率(即有效截面配筋率,不要搞错配筋率概念)一般在2.0%,全截面配筋率一般在2.0%以下(这句话相对于上句话似乎是废话,呵呵,但对于实际配筋时有很大方便)。
对于抗震梁(常见的为框架梁),除了控制上面的第二条外。
还需要满足,砼规11.3.1可知框架梁配筋率宜满足1.≤2.5%2.ρ≤α1ζbfc/fy ρ=(As'-As)/bhoξb=0.35(二、三级框架)=0.25(一级框架)考虑受压区钢筋作用______抗震框架梁梁端最大配筋率只是2.5%吗?抗震规范中,强规6.3.3条:6.3.3梁的钢筋配置,应符合下列各项要求:1梁端纵向受拉钢筋的配筋率不应大于 2.5%,且计入受压钢筋的梁端混凝土受压区高度和有效高度之比,一级不应大于0.25,二、三级不应大于0.35。
2梁端截面的底面和顶面纵向钢筋配筋量的比值,除按计算确定外,一级不应小于0.5,二、三级不应小于0.3。
高规中6.3.2条也有强制规定。
注意文中”且计入受压钢筋的。
“,这里关键一个“且”字,故“梁端纵向受拉钢筋的配筋率不应大于 2.5%”,只是必要条件,不能认为梁端纵向受拉钢筋的最大配筋率就是 2.5%。

The two regulations supporting each other, the < code > adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard; < rule > around the party discipline, disciplinary ruler requirements, listed as "negative list, focusing on vertical gauge, draw the party organizations and Party members do not touch the" bottom line ". Here, the main from four square face two party rules of interpretation: the first part introduces two party Revised regulations the necessity and the revision process; the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party; the third part introduces two party regulations modified the main changes and needs to grasp several key problems; the fourth part on how to grasp the implementation of the two regulations of the party. < code > and < Regulations > revised the necessity and revisedhistory of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines > and < Chinese Communist Party discipline and Punishment Regulations > column 1 by 2015 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation; follow the correct direction, grasp the limited goals, adhere to the party's leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the < code > and < rule >, reflects the party's 18 and the eighth session of the third, the spirit of the fourth plenary session, reflecting the experience of studying and implementing the General Secretary Xi Jinping series of important speech, reflects the party's eighteen years comprehensive strictly practice. (a) revised two regulations of the party need of < the ICAC guidelines > in < in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) > based on revised, the promulgation and implementation of January 2010, to strengthen the construction of the contingent of leading cadres play animportant role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too complicated, "eight prohibition, 52 are not allowed to" hard to remember, and also difficult to put into practice; the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements; the third is banned terms and discipline law, both with the party discipline, disciplinary regulations repeat and Criminal law and other laws and regulations repeat; the fourth is to "clean" the theme is not prominent, not for the existing problems, and is narrow, only needle of county-level leading cadres above. < rule > is in 1997 < Chinese Communist Party disciplinary cases (Trial) > based on revision, in December 2003 the promulgation and implementation, to strengthen the construction of the party play very important role. Along with the development of the situation, which many provisions have been unable to fully meet the comprehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and criminal law and other countries laws and regulations Repetition; two is the political discipline regulations is not prominent, not specific, for violation of the party constitution, damage theauthority of Party Constitution of misconduct lack necessary and serious responsibility to pursue; third is the main discipline for the leading cadres, does not cover all Party members. Based on the above situation, need to < the criterion of a clean and honest administration > and < rule > the two is likely to be more relevant regulations first amendment. By revising, really put the authority of Party discipline, the seriousness in the party tree and call up the majority of Party members and cadres of the party constitution of party compasses party consciousness. (II) two party regulations revision process the Central Committee of the Communist Party of China attaches great importance to two regulations revision . Xi Jinping, general books recorded in the Fifth Plenary Session of the eighth session of the Central Commission for Discipline Inspection, on the revised regulations < > made clear instructions. According to the central deployment, the Central Commission for Discipline Inspection from 2014 under six months begin study two regulations revision. The Standing Committee of the Central Commission for Discipline Inspection 4 review revised. Comrade Wang Qishan 14 times held a special meeting to study two regulations revision, amendment clarifies the direction, major issues of principle, path and target,respectively held a forum will listen to part of the province (area) secretary of the Party committee, Secretary of the Discipline Inspection Commission, part of the central ministries and state organs DepartmentThe first party committee is mainly responsible for people, views of experts and scholars and grassroots party organizations and Party members. Approved by the Central Committee of the Communist Party of China, on 7 September 2015, the general office of the Central Committee of the Party issued a notice to solicit the provinces (autonomous regions, municipalities) Party, the central ministries and commissions, state ministries and commissions of the Party (party), the General Political Department of the military, every 3 people organization of Party of two regulations revision opinion. Central Commission for Discipline Inspection of extensive solicitation of opinions, careful study, attracting, formed a revised sent reviewers. In October 8 and October 12, Central Committee Political Bureau Standing Committee and the Political Bureau of the Central Committee After consideration of the two regulations revised draft. On October 18, the Central Committee of the Communist Party of China formally issued two regulations. Can say, two laws amendment concentrated thewisdom of the whole party, embodies the party. Second, < code > and < Regulations > revision of the basic principles of two party regulations revision work and implement the party's eighteen, ten eight plenary, the spirit of the Fourth Plenary Session of the Eleventh Central Committee and General Secretary Xi Jinping important instructions on the revised < low political criterion > and < Regulations >, highlighting the ruling party characteristics, serious discipline, the discipline quite in front of the law, based on the current, a long-term, advance as a whole, with Bu Xiuding independent < rule > and < rule >. Main principle is: first, adhere to the party constitution to follow. The constitution about discipline and self-discipline required specific, awaken the party constitution of party compasses party consciousness, maintaining the authority of the constitution. General Secretary Xi Jinping pointed out that "no rules, no side round. Party constitution is the fundamental law, the party must follow the general rules. In early 2015 held the eighth session of the Central Commission for Discipline Inspection Fifth Plenary Session of the 16th Central Committee, Xi Jinping again pointed out that constitution is the party must follow the general rules, but also the general rules." the revision of the< code > and < rule > is Method in adhere to the regulations established for the purpose of combining rule of virtue is to adhere to the party constitution as a fundamental to follow, the constitution authority set up, wake up the party constitution and party rules the sense of discipline, the party constitution about discipline and self-discipline specific requirements. 4 second is to adhere to in accordance with the regulations governing the party and the party. The Party of rule of virtue "de", mainly refers to the party's ideals and beliefs, excellent traditional style. The revised the < code > closely linked to the "self-discipline", insisting on the positive initiative, for all members, highlight the "vital few", emphasized self-discipline, focusing on the morality, and the majority of Party members and the ideological and moral standards. The revised < > Ji method separately, Ji, Ji Yan to Method, as a "negative list", emphasizing the heteronomy, focusing on vertical gauge. Is this one high and one low, a positive reaction, the strict party discipline and practice results transformation for the integration of the whole party to observe moral and discipline requirements, for the majority of Party members and cadres provides benchmarking and ruler. Third, insist on to. In view of the problems existing in theparty at the present stage, the main problems of Party members and cadres in the aspect of self-discipline and abide by the discipline to make clearly defined, especially the party's eighteen years strict political discipline and political rules, organization and discipline and to implement the central eight provisions of the spirit against the four winds and other requirements into Disciplinary provisions. Not one pace reachs the designated position, focusing on in line with reality, pragmatic and effective. After the revision of major changes, major changes in the < code > and < rule > modified and needs to grasp several key problems (a) < code > < code > adhere to according to regulations governing the party and party with morals in combination, for at the present stage, the leadership of the party members and cadres and Party members in existing main problems of self-discipline, put forward principles, requirements and specifications, showing Communists noble moral pursuit, reflected at all times and in all over the world ethics from high from low 5 common requirements. One is closely linked to the "self-discipline", removal and no direct relation to the provisions of . the second is adhere to a positive advocate, "eight prohibition" 52 are not allowed to "about the content of the" negative list moved into synchronizationamendment < cases >. Three is for all the party members, will apply object from the leadership of the party members and cadres to expand to all Party members, fully embodies the comprehensive strictly required. The fourth is prominent key minority, seize the leadership of the party members and cadres is the key, and put forward higher requirements than the ordinary Party members. Five is to simplify, and strive to achieve concise, easy to understand, easy to remember. The revised < code > is the ruling Party since the first insists on a positive advocate forAll Party members and the self-discipline norms, moral declaration issued to all members of the party and the National People's solemn commitment. > < criterion of a clean and honest administration consists of 4 parts, 18, more than 3600 words. After the revision of the < code >, a total of eight, 281 words, including lead, specification and Party member cadre clean fingered self-discipline norms, etc. Part 3 members low-cost clean and self-discipline, the main contents can be summarized as "four must" "eight code". Lead part, reiterated on ideal and faith, fundamental purpose, the fine traditions and work style, noble sentiments, such as "four must" the principle of requirements, strong tone of self-discipline, The higher request for 6 andsupervised tenet, the foothold in permanent Bao the party's advanced nature and purity, to reflect the revised standards requirements. Members of self-discipline norms around the party members how to correctly treat and deal with the "public and private", "cheap and rot" thrifty and extravagance "bitter music", put forward the "four norms". Party leader cadre clean fingered self-discipline norms for the leadership of the party members and cadres of the "vital few", around the "clean politics", from civil servant of the color, the exercise of power, moral integrity, a good family tradition and other aspects of the leadership of the party members and cadres of the "four norms" < > < norm norm. "The Party member's self-discipline norms" and "party members and leading cadre clean fingered self-discipline norms," a total of eight, collectively referred to as the "eight". "Four must" and "eight" of the content from the party constitution and Party's several generation of leaders, especially Xi Jinping, general secretary of the important discussion, refer to the "three discipline and eight points for attention" statements, and reference some embody the Chinese nation excellent traditional culture essence of epigrams. (2) the revised regulations, the main changes in the revised Regulations > to fully adapt to thestrictly requirements, reflects the according to the regulations governing the law of recognition of deepening, the realization of the discipline construction and Jin Ju. < rule > is party a ruler, members of the basic line and follow. And the majority of Party members and cadres of Party organizations at all levels should adhere to the bottom line of thinking, fear discipline, hold the bottom line, as a preventive measure, to keep the party's advanced nature and purity. 1, respect for the constitution, refinement and discipline. Revised < rule > from comprehensive comb physical constitution began, the party constitution and other regulations of the Party of Party organizations and Party discipline requirements refinement, clearly defined in violation of the party constitution will be in accordance with regulations to give the corresponding disciplinary action. The original 10 categories of misconduct, integration specification for political discipline, discipline, honesty and discipline masses Ji Law and discipline and discipline and other six categories, the content of < rule > real return to Party discipline, for the majority of Party members and listed a "negative list. 7 2, highlighting the political discipline and political rules. > < Regulations according to the stage of the discipline of outstandingperformance, emphasizing political discipline and political rules, organization and discipline, in opposition to the party's leadership and the party's basic theory, basic line, basic program and basic experience, the basic requirement of behavior made prescribed punishment, increase the cliques, against the organization such as violation of the provisions, to ensure that the central government decrees and the Party of centralized and unified. 3, adhere to strict discipline in the law and discipline In front, Ji separated. Revised < Regulations > adhere to the problem oriented, do Ji separated. Any national law existing content, will not repeat the provisions, the total removal of 79 and criminal law, repeat the content of the public security management punishment law, and other laws and regulations. In the general reiterated that party organizations and Party members must conscientiously accept the party's discipline, die van comply with national laws and regulations; at the same time, to investigate violations of Party members and even criminal behavior of Party discipline and responsibility, > < Regulations distinguish five different conditions, with special provisions were made provisions, so as to realize the connection of Party discipline and state law. 4, reflect Wind building and anti-corruptionstruggle of the latest achievements. < rule > the party's eighteen years implement the spirit of the central provisions of the eight, against the requirements of the "four winds" and transformation for disciplinary provisions, reflecting the style construction is always on the road, not a gust of wind. In the fight against corruption out of new problems, increase the trading rights, the use of authority relatives profit and other disciplinary terms. Prominent discipline of the masses, the new against the interests of the masses and ignore the demands of the masses and other disciplinary terms and make provisions of the disposition and the destruction of the party's close ties with the masses.Discipline to protect the party's purpose. 8 of these regulations, a total of three series, Chapter 15, 178, more than 24000 words, after the revision of the regulations a total of 3 series, Chapter 11, 133, 17000 words, divided into "general" and "special provisions" and "Supplementary Provisions" Part 3. Among them, add, delete, modify the provisions of the proportion of up to nearly 90%. 1, the general general is divided into five chapters. The first chapter to the regulations of the guiding ideology, principles and scope of application of the provisions, highlight the strengthening ofthe party constitution consciousness, maintenance the authority of Party Constitution, increase the party organizations and Party members must abide by the party constitution, Yan Centralized centralized, would examine at all levels of the amended provisions implementing and maintaining Party discipline, and consciously accept the party discipline, exemplary compliance with national laws and regulations. The second chapter of discipline concept, disciplinary action types and effects of the regulations, will be a serious warning from the original a year for a year and a half; increase the Party Congress representative, by leaving the party above (including leave probation) punishment, the party organization should be terminated its representative qualification provisions. The third chapter of the disciplinary rules of use prescribed in the discipline rectifying process, non convergence, not close hand classified as severely or heavier punishment. "Discipline straighten "At least eighteen years of five years, these five years is to pay close attention to the provisions of the central eight implementation and anti -" four winds ". The fourth chapter on suspicion of illegal party disciplinary distinguish five different conditions, with special provisions were madeprovisions, to achieve effective convergence of Party and country 9 method. < rule > the provisions of Article 27, Party organizations in the disciplinary review found that party members have committed embezzlement, bribery, dereliction of duty dereliction of duty and other criminal law act is suspected of committing a crime shall give cancel party posts, probation or expelled from the party. The second is < Regulations > Article 28 the provisions of Party organizations in the disciplinary review But found that party members are stipulated in the criminal law, although not involved in a crime shall be investigated for Party discipline and responsibility should be depending on the specific circumstances shall be given a warning until expelled punishment. This situation and a difference is that the former regulation behavior has been suspected of a crime, the feeling is quite strict, and the latter for the behavior not involving crime, only the objective performance of the provisions of the criminal code of behavior, but the plot is a crime to slightly. < Regulations > the 29 provisions, Party organizations in the discipline review found that party members and other illegal behavior, affect the party's image, the damage to the party, the state and the people's interests, we should depend on the situationSeriousness given disciplinary action. The loss of Party members, seriously damaging the party's image of behavior, should be given expelled from the party. At this article is party member is in violation of the criminal law outside the other illegal acts, such as violates the public security administration punishment law, customs law, financial laws and regulations behavior. The fourth is < cases > Article 32 stipulates, minor party members and the circumstances of the crime, the people's Procuratorate shall make a decision not to initiate a prosecution, or the people's court shall make a conviction and exempted from criminal punishment shall be given within the party is removed from his post, probation or expelled from the party. Party members and crime, sheets were fined in accordance with For acts; the principal Ordinance amended the provisions of the preceding paragraph. This is the new content, in order to achieve Ji method effective convergence. Five is < > the thirty third article 10 of the provisions, the Party member due to an intentional crime is sentenced to criminal law (including probation) sheets or additional deprivation of political rights; due to negligence crime and was sentenced to three years or more (excluding three years) a penalty, shall give expelled punishment. Due to negligence crime is convictedand sentenced to three years (including three years) in prison or be sentenced to public surveillance, detention, shall in general be expelled from the party. For the individual may not be expelled from the party, should control Approval. This is followed and retained the original > < Regulations the provisions of punishment party authorization rules and report to a level party organizations. For is "party members with criminal acts, and by the criminal punishment, generally should be expelled from the party". The fifth chapter of probationary Party member of the discipline and discipline after missing members of the treatment and punishment decisions, such as the implementation of the provisions, clear the related party discipline and punishment decision made after, for duties, wages and other relevant alteration formalities for the longest time. 2, sub sub section will the original regulations of10 categories of acts of violation of discipline integration revised into 6 categories, respectively, in violation of the punishments for acts of political discipline "in violation of discipline behavior of punishment" in violation of integrity of disciplinary action points "of violation punishments for acts of mass discipline" "the violation of work discipline, punishment" in violation of discipline of life behaviorpunishment "6 chapters. 3, annex" Supplementary Provisions "clear authority making supplementary provisions of, cases of interpretative organ, as well as regulations implementation time and retroactivity etc.. 11 (3) learning understanding > < regulations needs to grasp several key problems The first problem -- about the violation of political discipline behavior > < new ordinance chapter 6 the political discipline column for the six disciplines, that is the main opposition to Party leadership and the opposition of the basic theory, basic line, basic program and basic experience, basic requirements of misconduct made provisions of the disposition, especially the eighteen since the CPC Central Committee put forward the Yan Mingzheng treatment of discipline and political rules requirements and practical achievements transformation for Discipline article, increase the false debate central policies, cliques, against the organization review, make no discipline of the principle of harmony terms. These are the party's eighteen years in comprehensive strictly Process combined with the practice of rich content. (1) false debate the central policies and undermine the Party of centralized and unified the problem is made in accordance with the provisions of the party constitution. Constitution in general programme requirements。
