Formula. At the same time, the article raised the seismic reduction factor formula for the SSDI system.The paper adopts finite element method based on the ANSYS procedure, and realizes the simulation of soil constitutional relationship through choosing Davidenkov soil model with proper parameters and using restartup method in ANSYS. Then, the procedure makes the soil nonlinearity simulation come true byusing parameter design language of APDL. Element Combin14 is be used to simulate viscoelastic boundary and radiation damping effect. At the same time, it presents integrated damping matrix for considering the coupling of different damping of soil and structure.

In this dissertation, many works have been done on the basis of the summarization of the merits of all kinds of meshless methods after a large number of relevant references are read and studied. The basic ideas, principles of meshless methods and their development in the recent years are introduced synoptically. Applications of Element-free Galerkin method in elastic foundation plate are studied deeply and some useful conclusions are obtained as follows:(1) Comparisons between numerical solutions and analytical solutions for several different styles of weight functions, including Gaussian weight function, spline weight function and singular weight function etc, are performed. The results show that Gaussian weight function is the best one.(2) Ranges of relevant parameters for Gaussian weight function are given.(3) Influences of nodal distribution schemes and the number of Gaussian integrated dots on computational results are discussed.
