摘　　要：根据隔震理论,结合SAP2000软件对某工程进行了隔震设计。通过对工程的分析,得出:1)隔震后,结构的自振周期变大,地震作用大大降低;2)隔震后,由于结构的水平位移集中在隔震层,使得基底剪力、层间加速度大大降低;3)纵向地震作用下的隔震效果要优于横向地震作用;4)隔震后,上部结构抗震设防烈度可按降一度设计。Based on the theory of isolation and SAP2000 software,the isolation design of a project was carried out.Through the analysis of the project,it was concluded that:1) after isolation,the natural vibration period of the structure became larger and the seismic action decreased greatly;2) after isolation,the base shear force and acceleration between layers were greatly reduced because the horizontal displacement of the structure was concentrated in the isolation layer;3) the isolation effect under longitudinal earthquake action was better than that under transverse earthquake;4) After isolation,the seismic fortification intensity of superstructure can be reduced by one degree.
