平面不规则结构的弹塑性时程分析

Elastic-plastic Time History Analysis of Irregular Plane Structure

针对平面不规则结构的特点,结合现行规范,参考常用抗震分析方法,提出对平面不规则结构进行多方向弹塑性时程分析的观点。通过对某工程实例的弹塑性时程分析,探讨了该类结构在不同方向罕遇地震作用下的地震反应,分析了塑性饺在不同构件中的发展情况及在整个结构中的分布情况,研究了某些主要承重构件在不同方向的受力性能。

Referring to the present seismic analysis methods and considering the characteristic of irregular plane structure and Code for seismic design of building, this research states a viewpoint that the irregular plane structure should be designed in different seismic directions. It is concluded by the elastic -plastic time history analysis to a representative structure, through which we discuss the seismic reaction of different directions, analyze the developing and distribution of the plastic hinges, and take a further research on different seismic responses of some prime bearing members.
