Numerical Parametric Study on the Cyclic Performance of Trapezoidally Corrugated Steel Shear Walls

Corrugated steel shear wall (CSSW) has higher ductility, energy dissipation capacity and toughness compared to the conventional steel plate shear wall (SPSW). The corrugation steel plate can be either installed vertically or horizontally. In recent decades, several experimental and numerical studies have investigated the effect of the corrugation angle, infill plate thickness and openings on the cyclic behavior of the horizontally-corrugated steel shear walls. However, to date, the behavior of the vertically-corrugated steel shear walls has not been fully studied. Thus, this paper aims to investigate numerically the cyclic behavior of the vertically-corrugated steel shear walls. The corrugation angle (30°-120°), infill plate thickness (1.25, 2, 3 mm), and the height-to-width (H/B) ratios of the walls (0.5, 0.8, and 1.2) were the parameters of this study. The influence of these parameters on the hysteresis behavior, toughness, and energy dissipation capacities of the CSSWs are investigated using 35 finite element (FE) models developed by ABAQUS/Standard. The FE results reveal that increasing the corrugation angle can improve the energy dissipation capacities and toughness of the CSSWs up to 15% and 5.8%, respectively. Furthermore, increasing the infill plate thickness and decreasing H/B ratios can significantly enhance the ultimate load, toughness, and energy dissipation capacities.
