- 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。
