摘要
采用多模态Pushover分析法,能够充分考虑高阶振型对结构的影响和结构进入弹塑性阶段后振型会发生变化这两个因素。采用了多模态Pushover分析法进行研究,结构选取某市华润中心住宅,按照《中国地震动区划图》,以动力时程分析的计算结果为标准,采用MPA、MMPA和IMPA法进行了抗震性能分析,在极罕遇地震作用下,探讨了三种方法运用在剪力墙结构抗震分析的差异。
Multi-mode Pushover analysis method adopted could enable the consideration on the influence of higher modes and the change of mode in elastic-plastic phases. In this paper, multi-mode Pushover analysis method was adopted. A Huarun center housing was selected as the structure to be studied, based on the calculating results of dynamic time-history analysis, the seismic performance was analyzed using MPA, MMPA. Under the extremely rare earthquake, the differences of three method analysis applying in seismic performance of the shear wall structure were discussed.
