| 摘 要： | 以ANSYS软件为上部空间结构计算平台,建立包含土、隔震层、基础、空间结构在内的整体三维模型,并通过与框架结构和框架隔震结构的水平地震效应做对比,分析了土-结构相互作用对滚珠隔震支座隔震效果的影响.结果表明：在水平地震作用下土-结构相互作用在一定程度上减弱了滚珠隔震支座的隔震效果,因此在隔震结构设计中考虑土-结构相互作用的影响是十分必要的.

| Abstract: | By using ANSYS software for the upper space structure, the whole 3D model including soil, isolation layer, base and spatial structure is established in the paper. And compared with the horizontal seismic effect of frame structure and frame isolated structure, the influence of soil-structure interaction（SSI） on the isolating effect of ball seismic isolation bearing is analyzed. The results indicate that SSI weakens the isolating effect to some extent under horizontal seismic action,so it is found to be necessary to consider SSI in the isolated structure design. |
