楼梯参与空间分析的RC框架结构静力弹塑性分析

Pushover analysis of RC frame structure with staircase involved

基于有限元分析软件,通过Pushover分析方法,对比分析罕遇地震作用下楼梯参与空间分析的框架模型和结构传统设计模型的结构响应,并分析二者和楼梯偏置框架模型的屈服机制,评价其抗震性能。

Based on the finite element analysis software and the pushover analysis method, the inten- tion is to analyze the differences of structural response between the model whose staircases take part in spatial analysis and the one designed in traditional methods, and to evaluate seismic performance by analyzing the yield mechanism of such two modals and the one whose staircase eccentrically placed.
