Abstract：The mixed structural system with steel and concrete composite columns and reinforced concrete (RC) shear walls exhibit excellent mechanical behavior. In order to study the seismic performance of the composite structure with RC shear walls and composite frames, the secondary development in ABAQUS was performed to achieve the user materials model using the user subroutine based on the layered shell element and nonlinear fiber beam element. The RC shear walls and composite frames were simulated by layered shell element and fiber beam element, respectively. The numerical simulation was carried out to study the cyclic performance of composite frames with concrete-filled steel tubular(CFST) columns, the mixed structures with CFST columns and steel reinforced concrete (SRC) columns and RC shear walls, respectively. The results obtained from the calculation are in good agreement with those from the experiment. The hysteresis behavior character and failure modes of the composite shear walls were analyzed and compared between test and simulation, and it was shown that the tested typical crack distribution of the walls are similar with the numerical results. The research shows that the layered shell element and fiber beam element can simulate hysteretic behavior of the composite shear walls more accurately and effectively, and it can describe the development of shear crack reasonably. The proposed approach in this paper is reference to simulate the seismic behavior of highrise buildings with steel and concrete mixed structural system effectively and accurately.
