Abstract :
Steel plate shear walls (SPSWs) are lateral resisting systems in steel structures. Creating an opening in the steel plate can affect the overall performance of the system. In this study, the performance of SPSW with openings, without stiffeners and eccentric braces at the edges of the openings has been investigated. Eccentric braces are used in the leading models to control the buckling of the steel plate at the opening edge. For the design of the models, the Iran Steel and 2800 Code were used, and for the numerical modeling, the ABAQUS finite element software and cyclic loading were used, and the investigated parameters included the response (base shear-drift), stiffness, damping, and dissipation energy. The results of numerical models showed that the use of eccentric braces in the opening edge leads to a 15% reduction in the base shear compared to the traditional SPSW model, and in purposed model, the stiffness reduction is almost the same as in the traditional SPSW model. The damping and energy parameters in the designed model have increased compared to the SPSW model, which indicates the increase in the capacity of the structure in energy consumption
