Based on reliability theory , the current seismic design code gbj11 - 89 and the previous research results of the same occupation , the seismic reliability analysis and the seismic design for the reinforced concrete frames are studied in this thesis . the major contents are summarized as follows : ( 1 ) seismic reliability of reinforced concrete beams designed following the current seismic design code is analyzed 本文以可靠度理论为基础，结合现行建筑抗震设计规范（ gbj11 - 89 ） ，在广泛借鉴国、内外同行研究成果的基础上，针对钢筋混凝土框架结构构件和体系抗震可靠度分析与设计的一系列问题进行了研究，主要研究内容为： （ 1 ）针对按现行建筑抗震设计规范设计的钢筋混凝土梁进行抗弯、抗剪可靠度分析。
Furthermore , comparing between the results calculated by the program and that of the test indicate that they are analogical . using the program , both the model structure and the prototype of the longitudinal frame - shear wall structure system of main factory building in a large thermal power plant are analyzed , from which we get the regular pattern of earthquake resistant behaviors of this kind of structure and propose the recommends for b oth s eismic d esign and c onstruction 应用该程序，本文对某大型火电厂钢筋混凝土结构主厂房纵向框架-剪力墙结构体系的试验模型和原型结构进行了分析比较，得到了这类结构抗震性能的一般规律，提出了一些新的抗震设计理念与构造建议；同时结合研究成果，为我国现行《建筑抗震设计规范》中基于承载力的抗震设计方法提出了一些修订建议。
This paper firstly compares the provisions about torsion effect and anti - torsion design in several codes ( the 89 and 01 chinese code for seismic , and some other countries " codes ) ； according to the 89 and 01 code for seismic design of buildings , the paper designs six multi - storied irregular rc spatial frames , which respectively situated at the area of fortification intensity 7 , 8 and 9 ； then compare with 89 , 01 code structures to reinforce bar difference and reason analyse . at the foundation above , using the program based on the column - beam element of fiber model , input several ground motion records , which are selected according to the demand of code , to carry the structures " three - dimensional nonlinear analysis in two perpendicular directions at the same time . at the end , the paper sums up the calculation results , reviews the whole performance and analyse the difference reason of this type of structures under 本文对比了我国新、旧建筑抗震设计规范（ gb50011 - 2001 、 gbj11 89 ）以及国外设计规范（或指南）中关于结构扭转效应与抗扭设计的相关规定；按照89 、 01抗震规范的有关规定，分别设计了设防烈度为7度、 8度、 9度的共6个钢筋混凝土平面不规则框架结构，对比了结构的配筋差异及原因分析，在此基础上，利用纤维模型梁柱单元的三维非线性动力分析程序，在设防地震作用和罕遇地震作用水准下选择适当的地震波作为输入，对结构进行了双向地震作用下的三维非线性动力反应分析，考察了按照89 、 01规范设计的这一类不规则框架结构的总体抗震性能及差异，并对产生这些差异的原因进行了分析；考察了结构在中震和大震作用下抗扭设计方法和措施的有效性，对结构在平?扭耦联振动下能否达到“中震可修” 、 “大震不倒”的抗震设防目标进行了初步评价。
Analyzing predominate period of ground motion . using the standard design response spectrum in code for seismic design of buildings , one can estimate the seismic response according the site classification . this approach only uses to estimate the effect of the first order mode 一般建筑结构按现行《建筑抗震设计规范》中规定的场地类别套用规范标准设计反应谱确定设计地震动反应谱，这一方法只能初略地考虑场地第一振型的影响效应(严格地讲，基底开放性土体不存ws在振型效应） 。
According to the code for aseismatic design of building structure ( gbj11 - 89 ) , the seismic base - shear method has always been used to calculate the seismic response of building structures . in those structures , their weights and rigidities equally distribute along their heights which do not exceed 40m , and their deformations are mostly the shearing type ( when the structures " ratio of height and width are smaller than 4 ) 我国《建筑抗震设计规范》 ( gbj11 ? 89 )中规定，对于重量和刚度沿高度分布比较均匀、高度不超过40m ，并以剪切变形为主(房屋高宽比小于4时)的结构，可采用近似计算法，即底部剪力法来计算其地震响应。
