隔震层中加入阻尼器后地震响应变化研究

摘要

This paper in the finite element software SAP2000 to establish finite element model of the buildinf,and to join in the isolation layer and without seismic response of the damper made a comparative study of the system. The research results show that in the structure of the isolation layer after addinf damper can sifnificantly reduce the displacement of isolation layer,and the structure of the internal force of the acceleration has increases accordinfly.%利用 SAP2000有限元软件，建立了某框架隔震建筑物的有限元模型，对比分析了在隔震层中加入与未加入阻尼器的地震响应情况，研究结果表明，在建筑物的隔震层中加入阻尼器能大幅减小隔震层的位移，同时建筑物的内力加速度都有相应增大的现象。
