Abstract

Abstract

Anisotropic elastic- plastic model of layered soil and composite foundation with flexible columns is established tosolve seismic response analysis of composite foundation in layered soil. The doubly asymptotic mult-i directional transmittingboundary for transversely isotropic medium is formed. Based on anisotropic elastic- plastic model of composite foundation andlayered soil, the dynamic FEM program of layered, transversely isotropic medium is developed according to the characteristicof earthquake response analysis for composite foundation. The seismic response analysis of the composite foundation inShanghai is carried out using the developed FEM program. From analysis results, it is shown that the dynamic FEM model oflayered, transversely isotropic composite foundation is feasible and applicable. And the results show that it is necessary totake account of anisotropy of composite foundation in the seismic analysis of composite foundation.
