不规则建筑隔震结构的抗震性能分析

Seismic performance of irregular isolation structure

利用SAP2000软件建立基础隔震结构、层间隔震结构以及传统的抗震结构的分析模型。通过对三种结构模型进行振型反应谱分析和弹性时程分析,评估和对比这三种结构楼层层间位移和层间位移角。结果表明:层间隔震结构抗震效果最好。

Based on the finite element software SAP2000 base isolation layer,interval isolation layer and the traditional anti-seismic structure model are set up. By means of executing the mode-superposition response spectrum analysis and elastic time-history analysis on the above three structure modals to evaluate and compare the inter-layer displacement and angle displacement between the layers of the above three structure modals.The results show that the interval isolation layer structure seismic performance works best.
