| 摘 要： | 结合某多塔高层隔震结构,采用弹性时程分析方法,分析了隔震结构在多遇地震和罕遇地震作用下的响应。主要包括自振周期、层间剪力、倾覆力矩和楼层位移等内容。结果表明,与非隔震情形相比,结构的自振周期明显增大,地震作用得到了较大的衰减。结构在地震作用下的隔震效果明显,楼层剪力及倾覆力矩均得到折减,在罕遇地震作用下隔震效果尤为显著。层间位移主要集中在隔震层,上部结构的层间位移几乎为零。

| Abstract: | The seismic analysis of a high-rise isolated structure with multi-tower under frequent earthquake and rare earthquake was carried out using time history method,including natural vibration,story shear force,overturning moment,story drift and so on.The results show that compared with non-isolated case,natural vibration period of the isolated structure increases obviously and seismic action decreases.Story shear force and overturning moment decrease,especially under rare earthquake.Story drift is mainly centralized at isolator layer,which approaches zero on superstructure. |
