Finite element analysis on seismic behavior of steel frame-steel reinforced concrete lateral resistance wall structure

The ABAQUS finite element software is used to simulate the horizontal mechanical behavior of steel frame-steel reinforced concrete lateral resistance wall structure and analyze influencing factors. The parameters include the steel ratio of shape steel infill lateral resistance wall, the axial compression ratio of frame columns and the aspect ratio of lateral resistance wall. The results show that the lateral stiffness and carrying capacity of structural system raise as the steel ratio of shape steel infill wall increase. With the axial compression ratio of columns increase, structural system has little change in the lateral stiffness, while the bearing capacity decreases and the torsional constraint for the frame columns is enhanced gradually. With the aspect ratio of lateral resistance wall reduces, the lateral stiffness and bearing capacity of structural system increase, while the ductility decreases gradually.
