| 摘 要： | 连续模态Pushover分析(Consecutive Modal Pushover,简称CMP)是一种能够考虑结构高阶振型的Pushover分析方法.为研究该法是否适用于钢交错桁架结构的抗震性能评估,分别时10层、15层和20层钢交错桁架结构体系进行CMP分析和非线性时程分析,并通过比较由CMP分析和非线性时程分析所得结构的反应,对CMP分析法提出相应的改进方案.分析结果表明,改进后的CMP分析法对于铜交错桁架结构的抗震性能评估是一种行之有效的方法.

| Abstract: | The consecutive modal pushover(CMP) is a new pushover procedure which can take into account higher-mode effects. The present study aims at validating CMP for the seismic performance evaluation of steel staggered truss through comparison with nonlinear response histo-ry analysis of 10,15 and 20 storey steel staggered tress. And an improved CMP procedure has been put forward. It is demonstrated that the improved CMP procedure is able to accurately predict the seismic demands of steel staggered truss. |
