[摘要] 基于有限元结构分析软件SAP2000，建立9层钢筋混凝土框架结构在基础隔震与普通抗震两种情况下的三维模型，分别对模型模拟输入几组地震波工况，然后采用时程分析的方法进行分析计算。在不同的地震波工况下，分析得出隔震结构与非隔震结构的位移、加速度与楼层剪力的变化特性，并对两种结构的各种特性做出对比，验证了基础隔震结构的可行性和优越性。

Abstract: Based on the finite element analysis using SAP2000 software, tw0 3D models of nine-floor frame structure respectively under condition of isolation and none-isolation were set up. Several seismic wave conditions were inputted to the two models and then the models were calculated respectively by the time-history method. Under different seisrmc wave conditions, variation characteristics of floor shear, displacement and acceleration of the isolation structure and none-isolated structure were obtained, meantime, the comparison between them was made. In tlus way, feasibility and superiority of base-isolated structure were verified.
