摘要
本文首先建立层间隔震结构的结构动力模型并得出层间隔震结构的运动方程,然后利用大型结构有限元分析软件SAP2000对12层带裙房层间隔震框架结构在多遇和罕遇地震作用下分别进行动力时程分析,得出结构在地震作用下的层间位移、楼层剪力和楼层加速度,并与未采用层间隔震的抗震结构进行了对比,以评价层间隔震结构的减震效果,得到一些有益的结论。
In this paper,the structural dynamic model for the story isolation frame is established and the dynamic equation of the system is obtained.By using the large-scale structural finite element analysis software SAP2000,the dynamic time-history analysis of 12-layer story isolation frame structure with podium is carried out in frequently occurred earthquake and seldomly occurred earthquake respectively.The earthquake responses of the structure,including the displacement,shear force and acceleration of each floor,are calculated and compared with those of the same structure without story isolation,to assess the damping effect of story isolation structure,some useful conclusions are obtained.
