Abstract
Corrugated steel plate shear wall system (CSPSW) is one of the lateral load resisting systems, which in some cases has better seismic performance than the steel plate shear wall system. In this study, the seismic performance of the corrugated steel shear wall system was investigated. The variables of the present study are the angle of corrugated steel plate (0 to 30 degrees), percentage of steel plate openings (10, 20, and 30), and the number of openings (1, 2, 3, and 4). Abaqus finite element software was used for modeling and analysis. A total of 91 steel shear wall models were subjected to 100 mm displacement and were analyzed by the pushover method. The behavior of steel materials is considered as elastoplastic. The results showed that as the angle of corrugation increased, the yield and ultimate strength increased. The initial stiffness decreased with increasing angle of corrugation. Secondary stiffness also increased initially but decreased afterward, but the ductility decreased. With the increase in the percentage of openings, the yield, and ultimate strength decrease. The initial and secondary stiffness decreased, and the ductility first decreased and then increased. As the number of openings increases, the yield and ultimate strength decrease first and then increase.
