| 摘 要： | 推导得出了一个简化过渡界面单元的单元刚度矩阵．采用界面元-有限元的混合模型来模拟三堆土-结构体系，并采用一致边界来模拟波向无穷远城地基的传播作用．然后壕制了一个可用于进行三堆土-结构非线性地震反应分析的程序，并用谊程序对一框架结构进行了考虑土-结构相互作用影响的地震反应分析．最后总结了各种非线性因素和土-结构相互作用效应时结构地震反应的影响规律．图11。参9．

| Abstract: | A stiffness matrix of transition interface element was deduced, Mixed model for interface stress element-finite element method was adopted to simulate the spatial soil-structure system. And consistent boundary was selected to simulate the propagation of wave to exterior infinite media. A non-linear time history analysis program for computing the spatial soil-structure seismic response was compiled, and then the seismic response of a frame was computed with it. The laws of various non-linear and SSI effect on the structural seismic response were summarized based on the numerical results.1 1figs., 9refs. |
