本文概述了土与结构的相互作用问题,重点研究了地震时土与结构的相互作用问题。通过对六栋房屋分别座落在不同的地基上进行分析研究,得出不同地基对不同结构类型的高层建筑的地震反应的不同影响,进而给出了考虑和不考虑相互作用两种情况下结构的周期、剪力、地震力和位移的变化情况,有助于研究结构设计中抗震作用问题。 This paper summarizes the problem of soil-structure interaction and focuses on the interaction of soil and structure during earthquakes. Through the analysis and study of six houses located on different foundations respectively, the different influences of different foundations on the seismic response of high-rise buildings with different types of structures are obtained. Then the structures with or without considering the interaction are given The changes of the periodic, shear force, seismic force and displacement are helpful to study the anti-seismic effect of structural design.
