Abstract :
    The present work describes the theoretical study and numerical analysis on steel plate shear walls. Steel shear walls can be used as lateral load-bearing systems for buildings that require large-scale horizontal load capacity. The steel shear walls that are made from steel plates that in addition to increasing strength, ductility and energy absorption, are economical and cost-effective, and is widely used in tall building retrofitting of structures and tanks. The present study involves numerical analysis using experimental parameters for steel plate shear walls and comparing their results with together. In this study, a variety of shear wall samples with and without opening were modeled using ABAQUS finite element software and analyzed by applying the required parameters. The purpose of this study was to discussion the buckle behavior and bending deformations under the influence of dynamic loads with approach nonlinear behavior of materials and effect of opening in these systems with mentioned parameters. By comparing the results obtained in this study it can be seen that by creating opening on the steel shear wall and consequently increasing the diameter of the opening from 100 mm to 500 mm, the resistance is reduced by 28%. The results also show that for models without and with opening of 100, 300 and 500 mm, the buckling phenomenon occurs in forces of 3300, 3000, 2700 and 2400 KN, respectively, which results are shown in force-displacement diagrams as Hysteresis diagrams.
