With the rapid development of China's construction industry,the shear wall structure is more and more applied to the building. This paper uses the ABAQUS analysis software to simulate the shear wall structure with low cycle load, and analyzes and studies the seismic behavior of the shear wall with two kinds of connecting modes, cast-in-place and assembled. The hysteresis curves of two kinds of shear walls are obtained by simulation. The ultimate bearing capacity of fabricated shear wall members is slightly higher than the cast-in-place shear walls, which shows that the assembled shear wall has better seismic and energy dissipation capacity. The ductility coefficients of the two kinds of shear wall members are similar by the analysis of the displacement ductility coefficients. Compared with the two kinds of shear wall specimens, the initial stiffness of the assembled shear wall specimen is slightly larger than the cast-in-place specimen, and the stiffness of the cast-in-place shear wall specimen is relatively slow, and the two stiffness degeneration curve overlap gradually. The preliminary results show that the seismic performance of the assembled shear wall specimens satisfies the specification compared with the cast-in-place shear wall specimens.
