摘　　要：采用SAP2000结构分析软件,建立某15层大底盘框架结构的抗震结构模型、基础隔震及层间隔震模型,对三种模型在多遇和罕遇地震作用下进行非线性时程分析,对比隔震结构和抗震结构的周期、位移和加速度等变化情况,评判隔震效果,得到一些具有参考价值的结论。Structural analysis software SAP2000 was used to establish a model of fifteen-storey frame structure with anti-seismic structure,base isolation and the interlayer seismic isolation structure models.A non-linear time-history analysis of three models were done under the frequent earthquake and rare earthquake.it was compared the changes in cycle,displacement and acceleration of the isolation and aseismic structures and evaluated the isolation effect.It was obtained some valuable conclusions.

关 键 词：SAP2000 层间隔震 基础隔震 非线性时程分析
