Abstract

In this paper, the influence of soil-structure interaction(SSI) effects on maximum displacement response of low-medium rise reinforced concrete building with relatively high strength are studied. A practical procedure with a simplified model including nonlinear SSI effects to predict maximum displacement response is proposed. Shear force-displacement relation and damping factor including SSI effects are obtained by using maximum displacements response of simplified model and surface ground layer due to strong ground motions. The maximum response estimation due to strong earthquake motions is demonstrated using example models of reinforced concrete 5-story building and surface ground deposit. The validity of proposed procedure is examined in comparison with the results of nonlinear response analysis using 2-dimentional FEM model.
