（北京城建設計研究總院有限責任公司，北京 100037）[摘要] 基于有限元結構分析軟件SAP2000，建立9層鋼筋混凝土框架結構在基礎隔震與普通抗震兩種情況下的三維模型，分別對模型模擬輸入幾組地震波工況，然后采用時程分析的方法進行分析計算。在不同的地震波工況下，分析得出隔震結構與非隔震結構的位移、加速度與樓層剪力的變化特性，并對兩種結構的各種特性做出對比，驗證了基礎隔震結構的可行性和優(yōu)越性。

( Beijing Urban Engineering Design&Research Institute Co., Ltd., Beijing 100037, China)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.
