并联复合隔震结构的地震反应分析

Analysis of the Seismic Response of the Parallel Composite Isolation

本文根据建立的并联复合隔震结构计算模型,基于结构动力时程分析和静力弹塑性方法,编制了计算程序,对地震作用下传统抗震结构、纯橡胶隔震结构、摩擦滑移隔震结构和并联复合隔震结构的地震反应进行了对比分析。结果表明,隔震体系能够显著地降低结构的地震反应。

This paper gives a calculation model of the parallel composite isolation structure.Using the computer program based on dynamic time history analysis and pushover procedures,the seismic response of the anti-seismic structure,the laminated rubber isolation,the friction base isolation and the parallel composite isolation are calculated.The results show that isolation system can significantly reduce the seismic response.
