多层及高层房屋扭转耦联弹塑性地震反应的研究

简要介绍简化的空间模型弹塑性时程分析程序ＺＺＣ的编制原理，当楼板刚性时该空间模型可以退化为串联刚片系模型，应用该程序对均匀偏心结构和人有某层偏心的 局部偏心的结构从静力偏心距、基本平均频率、平扭频率比三个方面进行多层及高层房屋弹塑性平扭耦联地震反应的特性以及结构各构件的强度分布的要求等问题进行研究，得到了较好了的结果。

Study on inelastic torsional coupled seismic response of multistory and high rise buildings

A brief introduction to inelastic time history analysis program named ZZC is given for simplified space model which can be turned to series rigid plate model when the floor diaphragm is rigid. By using that program, inelastic earthquake response characteristic of asymmetric buildings with eccentricity in all stories and in one story only were studied in terms of the static eccentric ratio, the base lateral frequency and the frequency ratio of lateral to torsional. Meanwhile, the effect of strength distribution on inelastic response was studied and discussed.
