摘　　要：以一幢12层的框架结构为研究对象,以简化方法对地基约束作用进行模拟,并讨论基础埋深、楼板刚度对相互作用体系的整体刚度的影响;然后分别进行了刚性地基体系和相互作用体系的pushover分析及非线性时程分析,考察地震力沿模型体系竖向的分布特征,讨论适用于相互作用体系的侧向荷载加载模式。Simplified method is adopted to simulate the foundation soil＇ s restriction effect on a 12-story frame structure, and the effects of embedded depth of foundation and basement stiffness on the integral stiffness have been discussed. With the studies of the building by both pushover analysis and nonlinear dynamic analysis with and without considering soil-structure interaction, the distributions of seismic forces along structural vertical direction have been investigated, and the effects of various lateral load patterns on pushover analysis of soil-structure interaction system have been studied.
