By means of Ansys finite element analysis software, simulates the RC shear wall under different axial compression ratio, applies the load step document to simulate the low cycle repeated load, and studies the seismic performance of the 3 shear walls of 0.20, 0.25 and 0.30 axial compression ratio, including seismic bearing capacity, ductility, energy dissipation capacity, crack development patterns, etc.. The simulation results are in agreement with the experimental results of the solid wall with axial pressure ratio of 0.25 .
