摘　　要：以某7层隔震框架结构为例,以El-centro波和Taft波为激励,采用动态时程分析对该框架结构进行了罕遇地震作用下的弹塑性反应分析,结果表明采用基础隔震后,能够保证结构在罕遇地震作用下上部结构基本上处于弹性。With a base isolated seven-story frame structure as an example and E1-centro and Taft wave as the excitation, the dynamic time history analysis method is adopted to carry out the elasto-plastic response of the frame structure in considering the rare earthquake. The results indicate that the horizontal displacement focuses on isolation layer, upper structure can be assuranced in elastic state subjected to rare earthquake after using base isolation technology.

关 键 词：隔震 框架结构 弹塑性 恢复力特性
