结构抗震中的静力弹塑性(pushover)分析方法
|
摘要
Pushover分析方法是逐渐得到广泛应用的一种评估结构抗震性能的简化方法,已被引入我国新的建筑结构抗震规范.本文介绍了pushover分析的基本原理和实施pushover分析的关键问题,最后选用三种水平荷载模式和非线性时程分析进行了比较.
Pushover analysis is a simplified method for structure seismic evaluation,which is extensively used,and is recommended by the new national code of seismic design of buildings.The paper presents a concise introduction to the principle and several important problems of pushover analysis.In the end,comparison between nonlinear time history analysis and pushover analysis using three lateral load patterns is undertaken.
