中文摘要：
目前大跨空间结构抗震研究的分析模型主要是基于刚性地基假设．为了更好地反映空间结构在地震作用下的反应性能，有必要把上部屋盖与下部支承结构以及下部地基作为一个整体建模分析．土-结构相互作用在高层结构中研究得比较充分，空间结构研究土-结构相互作用则较少．本文从土结构相互作用模型、辐射阻尼以及地震动输入三方面对研究现状进行总结．考虑土-结构相互作用的空间结构抗震的深入研究将有助于空间结构的更合理的抗震设计．
英文摘要：
At present, the seismic analysis of spatial structure is assumed as rigid connected. It is necessary to model the spatial structure incorporating the roof, the supporting structure and the soil medium to reflect the real seismic performance under the seismic actions. The research on the effect of soil-structure interatction（SSI） on the seismic response of the spatial structure is in initial phase although it is studied a lot in the high rise buildings. This paper is to sum up the state of the art from the perspective of SSI model, the radiation damping and the earthquake input. The research on the seismic analysis of spatial structure incorporating the SSI is beneficial to the reasonable seismic design of spatial structures.
