摘 要: 将隔震结构地基土简化为弹性半空间模型 ,分析了土—结构相互作用对隔震结构地震响应的影响 .同时 ,分析了隔震体系地震响应随阻尼比及地震动频率变化而变化的规律 .分析结果表明 Regarding soil of foundation as the modle of elas tic halfspace,this paper analyses the influence of soil-structure interaction on the earthquake response of base-isolated structure.At the same time ,the rul e of earthquake response of isolated structure,which is changing with the dampi ng ratio and the frequency of earthquake is analyzed.The results show that the int eraction of soil-structure can not be neglected.
