摘要

摘要: 波纹钢板覆面冷弯型钢剪力墙是一种新型的侧向力抵抗体系，凭借高抗剪承载力、不可燃性等特点，近年来受到广泛关注。目前该类墙体的抗剪承载力主要通过试验方法确定，面板形式单一且缺乏理论依据。为此，针对波纹钢板剪切屈曲的理想破坏模式建立波纹钢板覆面墙体抗剪承载力理论计算方法，将墙体抗剪承载力通过面板的抗剪承载力进行近似替代，通过建立220组波纹钢板剪切屈曲荷载的有限元模型，对其进行计算及特征值屈曲分析，综合考虑波纹钢板的剪切屈曲强度和屈曲后强度，提出波纹钢板覆面墙体抗剪承载力的计算方法。该方法形式简单，计算准确度较高，可以对肋高15 mm左右的波纹钢板覆面墙体抗剪承载力进行预测。

Abstract: Corrugated steel sheet-sheathed cold-formed steel （CFS） shear walls are a new type of lateral force-resisting system. They have attracted extensive attention in recent years due to their high shear capacity and non-flammability. At present the shear capacity of such shear walls is mainly determined through experiments. There is limited variety in sheathing profiles and a lack of theoretical basis. To establish a design method for the shear capacity of corrugated steel sheet-sheathed shear walls， the shear capacity of shear walls was approximated by that of the sheathing instead. A total of 220 finite element models were developed to investigate the shear buckling load of corrugated steel sheets， and an eigenvalue buckling analysis was conducted. By considering both the elastic buckling strength and post-buckling strength of corrugated steel sheets， a calculation method for the shear capacity of corrugated steel sheet-sheathed shear walls was established. This method features a simple formulation and high computational accuracy， providing effective predictions for the shear capacity of walls sheathed with corrugated sheets having a rib height of approximately 15 mm.
