摘要:
为了研究低屈服点波形钢板剪力墙（corrugated steel plate shear wall，CSPSW）新型抗侧向荷载系统减震耗能性能，利用有限元软件ABAQUS，对16个CSPSW有限元模型进行横向单调和循环荷载作用下的减震耗能性能数值分析，并以波形钢板屈服强度和板厚为关键参数，综合分析其对结构抗侧性能、滞回性能、刚度退化、延性和能量耗散等性能的影响规律. 研究结果表明：低屈服点CSPSW与普通钢板剪力墙初始刚度相同，但抗侧性能弱于后者；与普通屈服强度CSPSW相比，低屈服点CSPSW滞回曲线更饱满，耗能性能更好，且延性更好；随着波形钢板屈服强度降低，低屈服点CSPSW延性和耗能性能均提高，结构水平刚度退化加快；随着波形钢板厚度增大，低屈服点CSPSW初始刚度和结构耗能性能均提高，承载能力变化较小.
Abstract: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.
