In order to study the seismic performance of low-yield-point corrugated steel plate shear walls (CSPSWs), a new type of lateral-resistant load system, the finite element software ABAQUS was used to numerically analyze the seismic energy dissipation behavior of 16 CSPSWs under lateral monotonic and cyclic loads. The yield strength and thickness of the infill CSPSWs were selected as the key parameters in the parametric study of the new wall system to assess their impact on the lateral resistance performance, hysteresis performance, stiffness degradation, ductility, and energy dissipation. The results show that the low-yield-point CSPSWs possess the same initial stiffness as that of the ordinary steel plate shear wall, but has a weaker lateral resistance than the latter. Compared with the ordinary-yield-strength CSPSWs, the low-yield-point CSPSWs is capable of developing a fuller hysteresis curve. The energy dissipation and ductility of the new wall system are also better than those of the ordinary-yield-strength CSPSWs. As the yield strength of the CSPSWs decreases, the ductility and energy dissipation of the low-yield-point CSPSWs increase, and the degradation of structural horizontal stiffness accelerates. As the thickness of the low-yield-point stress CSPSWs increases, the initial rigidity and structural energy dissipation increase, while the load-bearing capacity changes less.
