The role of soil-structure interaction on seismic behavior of reinforced concrete structures is investigated in this paper. Finite element approach has been adopted to model the interaction system, that consists of a reinforced concrete plane frame, soil deposit, and interface which represents the frictional surface between the foundation of the structure and subsoil. The analysis is based on the nonlinear characteristics of the materials and the elasto-plastic behavior of the frame members (beams and columns) is governed by a yield surface which is defined by ultimate strength of the axial force-bending moment interaction, while the cap model is adopted to govern the elasto-plastic behavior of the soil material. Results deduced from the dynamic analysis indicate that soil-structure interaction can have beneficial effects on structural behavior and this behavior is dependent on the characteristics of the soil and the interface conditions.
