Abstract
Shear walls are the commonly used lateral load resisting system. Shear wall system consists of a series of plane walls surrounding a service area to form a core. Reinforced concrete shear walls have been widely used in both concrete and steel buildings. Recently, shear walls consisting of steel frames with unstiffened flat steel plate (infill panels), blocking a panel of one storey height and one bay width, have been constructed. The objective of this research is to investigate numerically the behaviour of steel shear walls employing corrugated steel plates as infill panels, and to assess how the story shear is shared between the infill panel and the boundary frame columns. Shear wall models subjected to monotonic and cyclic loads are studied. The variable parameters are: panel width, corrugation angle, corrugation profile, infill plate thickness, and infill plate orientation with the horizontal. Results show that shear walls with corrugated infill panels (CPSW) exhibited 6 percent higher shear strength than shear walls with flat infill panels (FPSW). The panel width, the corrugation angle, and the corrugation profile have minimal effect on the strength of corrugated steel plate shear walls. For the models subjected to cyclic loading, the results have shown that CPSW dissipate more energy than FPSW. Although corrugated steel plate shear walls with thinner infill panels have reduced strength, they are more ductile than shear walls with thicker infill panels. In addition, the results have shown that CPSW with horizontal corrugated infill panels dissipate more energy and are more ductile than shear walls with oriented corrugated infill panels.
