Abstract: Due to outstanding ductility and high strength, the steel plate shear wall (SPSW) is recognized as a good lateral system for building structures; particularly as it interacts with earthquake resistant design. This study aims to reveal the dynamic and cyclic behavior of steel plated shear wall. Finite element method of analysis was implemented in order to simulate the behavior of such a wall structure. To determine the dynamic behavior of un-stiffened plate shear wall, two different analytical models were implemented. The post buckling strength of steel plate subjected to lateral loading was also employed. The story shear-drift diagrams of steel shear wall system were presented. The strength and ductility of the system obtained from the analysis were compared with those of steel shear wall tests reported before. The pertinent parameters of the steel shear wall system such as plate thickness, column and beam stiffness and the plate aspect ratio were recognized and their effects were recorded. The effect of stiffeners on the behavior of the SPSW was also investigated.
