摘　　要：将层间隔震和消能减震技术混合运用在大底盘框架结构中,利用结构有限元分析软件SAP2000对某10层大底盘单塔框架结构进行实例分析,分别建立结构的层间隔震模型和混合减震模型以及通常情况下的抗震结构模型,并分别进行在罕遇地震作用下的动力时程分析。通过层间位移、楼层剪力和楼层相对加速度的对比,不仅可以详细了解混合减震结构的减震性能,还可了解到一些非常有益的结论。In this article, the story isolation technology and energy dissipation technology mixed use in frame structure with a large podium. By using of structural finite element analysis software SAP2000, to establish the seismic structure and the story isolation and mixed-damping structure model, which has lO-layer single tower frame structure with a large podium, respectively. Then, the dynamic time- history analysis of single tower frame structure is carried out in seldomly occurred earthquake. By comparing of the displacement, shear force and acceleration of each floor, to evaluation isolation and dissipation performance of mixed-damping structure, and get some useful conclusions.
