| Abstract: | In this paper, the dynamical response of soil structure coupled system was studied by the continuum theory of soild fluid mixtures, the building foundation system subjected to rapid earthquake excitation were calculated by using finite element method.In the results, the deformation patterns and corresponding contour diagrams of pore pressure at various time levels are given, time variations of displacement in a certain node and shear stress in a certain element are also presented. The results of this study have provided an improved understanding of coupled behaviour of porous media. The procedure developed in this paper can be effectively used under a wide range of loading conditions from very slow quasi static to very rapid earthquake excitations. |
