Corrugated steel plate shear walls (CoSPSWs), which consist of corrugated infill steel wall panels and steel boundary frames, could be used as lateral force-resisting systems for mid- to high-rise buildings. In seismic design, the fundamental vibration period is generally estimated by empirical formulae corresponding to different types of lateral force-resisting systems. However, both the formulae in various design specifications and improved formulae proposed recently for steel shear walls with flat wall panels were not suitable and accurate for CoSPSWs since the difference in the load-carrying mechanism of steel shear walls with flat and corrugated wall panels respectively. Eigenvalue frequency analyses were conducted on a total of 60 validated CoSPSW finite element models with varying geometries, and results showed that fundamental periods estimated by current formulae were shorter than periods from the analyses, which might lead to the over-conservative and uneconomic design. Improved empirical formula was proposed for the fundamental period of CoSPSWs based on regression analyses. Simplified calculation method for calculating the fundamental period of CoSPSWs after the first trial design was proposed using the shear-flexure cantilever formulation, and validated through finite element analyses. Furthermore, influences of major geometric properties of CoSPSWs on the fundamental period was investigated.

由波纹填充钢板墙板和钢边界框架组成的波纹钢板剪力墙（CoSPSW）可用作中高层建筑的横向抗力系统。在抗震设计中，基本振动周期通常由对应于不同类型的横向抗力系统的经验公式估算。然而，由于平板和波形壁板钢剪力墙的承载机理分别不同，因此各种设计规范中的公式和最近针对带平板墙的钢剪力墙提出的改进公式均不适用于CoSPSW。特征值频率分析是对总共60个经过验证的CoSPSW有限元模型进行的，这些模型具有不同的几何形状，结果表明，当前公式估算的基本周期比分析周期要短，这可能导致设计过于保守和不经济。在回归分析的基础上，提出了改进的经验公式。提出了使用剪切挠曲悬臂梁公式简化首次试验设计后计算CoSPSWs基本周期的方法，并通过有限元分析进行了验证。此外，研究了CoSPSWs的主要几何性质对基期的影响。提出了使用剪切挠曲悬臂梁公式简化首次试验设计后计算CoSPSWs基本周期的方法，并通过有限元分析进行了验证。此外，研究了CoSPSWs的主要几何特性对基期的影响。提出了使用剪切挠曲悬臂梁公式简化首次试验设计后计算CoSPSWs基本周期的方法，并通过有限元分析进行了验证。此外，研究了CoSPSWs的主要几何性质对基期的影响。
