The widespread usage of corrugated steel plates as girders and steel shear walls necessitates the need for further investigation of these efficient structural members. Having significant initial stiffness, high capability of energy dissipation and special geometry are the fundamental reasons for this study. The nonlinear behavior of trapezoidal corrugated steel shear walls with rectangular opening has been studied in this paper. A series of corrugated and simple shear walls with and without opening regarding different angles of corrugation and different infill plat thicknesses have been investigated. This analytical study was conducted to compare the initial stiffness, ultimate strength, energy dissipation and force-displacement curves of corrugated steel shear walls. Additionally, the results show that utilizing trapezoidal corrugated panels increase initial stiffness, capability of energy dissipation and ductility, while reducing the ultimate strength of shear wall system with opening. In addition, corrugated steel shear wall postpones the ultimate strength and degradation point compared with corresponding unstiffened steel shear wall, which is highly beneficent seismic characteristic of these structural elements. Furthermore, the corrugated steel shear wall’s appropriate opening position is determined according to ultimate strength, initial stiffness and ductility of the models
