The corrugated steel plate shear wall (CSPSW) system is a lateral force-resisting system, about which many studies have been carried out in recent years. In the present study, the behavior of this system is investigated by pushover analysis. For this purpose, twenty CSPSWs structures are designed with width-to-height ratio (L/H) of 2.5, 2, 1.4, and 0.85, and the number of floors 1, 2, 4, 6, and 10 were designed and analyzed using the ABAQUS finite element software package. The results of this study show that the initial stiffness of CSPSWs is high and reaches its ultimate capacity at a thrust ratio of 0.1%; on the other hand, after the buckling in the infill plate, the stiffness and base shear of the plate shear wall (PSW) significantly decreases. Also, the results show that the infill plate tolerates a higher percentage of shear force before the buckling of the plate, but after buckling, the frame tolerates a higher percentage of the shear force. In multi-story structures, the boundary frame with shear performance in the lower floors has a more effective role in bearing shear force. Moreover, in the present study, an equation is presented for calculating the tension field inclination angle. According to the equation, the tension field inclination angle depends only on the PSW aspect ratio. Finally, a method is presented for estimating the uniform force–displacement curve of the single- and multi-story CSPSW systems. This method is obtained based on the corrugated plate-frame interaction (PFI) and was confirmed with the force–displacement curve of experimental specimens and numerical models.

波纹钢板剪力墙系统的墙-框架相互作用效应

波纹钢板剪力墙(CPSSW)体系是一种抗侧向力体系,近年来对其进行了大量研究。在本研究中,该系统的行为是通过推覆分析来研究的。为此,设计了 20 个 CSPSW 结构,宽高比 (L/H) 为 2.5、2、1.4 和 0.85,并设计和分析了 1、2、4、6 和 10 层的数量使用 ABAQUS 有限元软件包。本研究结果表明,CSPSWs 的初始刚度较高,在推力比为 0.1% 时达到其极限承载力;另一方面,填充板屈曲后,板剪力墙(PSW)的刚度和底剪力显着降低。还,结果表明,填充板在板屈曲之前承受更高百分比的剪切力,但在屈曲之后,框架承受更高百分比的剪切力。在多层结构中,较低楼层具有抗剪性能的边界框架在承受剪力方面具有更有效的作用。此外,在本研究中,提出了一个计算张力场倾角的方程。根据方程,张力场倾角仅取决于 PSW 纵横比。最后,提出了一种估计单层和多层 CSPSW 系统的均匀力-位移曲线的方法。该方法是基于波纹板框架相互作用(PFI)获得的,并通过实验样品的力-位移曲线和数值模型得到证实。
