Abstract:
Numerous structures which are involved in seismic soil-pile-structure interaction have been damaged، failure in piles or even collapsed that can’t predict. Because of difficult modeling in soil، pile، structure interaction prediction the response of structure is impossible. In this study with using the finite element Abaqus software tries to understand the effect of soil pile structure interaction in structure response. By using the time history of Elcentro، structure with different boundary conditions were analyzed and the response of them were compared. Models have different boundary condition such as fixed base، pile groups and pile raft. Also in this study the effect of mat in interaction was considered. At the final step the pile group reanalyze with weak soil to find out how the wrong estimation of soil strength can effect on structure response. Soil and structure have elasto plastic behavior and Mohr Colomb criteria were chosen for soil behavior. Moreover the separation and slippage was allowed between soil and pile interaction
