Investigating the Opening Dimensions, the Stiffness of the Boundary Elements and the Type of the Infill Plate on the Behavior of Steel Plate Shear Wall

The steel plate shear wall (SPSW) has always been of interest to designers and researchers as an efficient lateral loading system over the past few decades. In this study, three objectives were followed using the finite element method (FEM): a) investigating the effect of a circular opening on the behavior of steel shear walls and presenting the relationship between the ratio of the diameter of the hole to the height and the ultimate strength of the wall, b) the effect of increasing the stiffness of the beam and column elements on the behavior of steel shear walls and presenting the relationship between the effect of each increase on the ultimate strength of the wall, c) the effect of the infill plate made of different steel on the behavior of steel shear walls.The results of all models were extracted in terms of the ultimate strength, ductility, stiffness and energy absorption and compared with each other. Also, the relationships related to the effect of increasing the diameter and the stiffness of the boundary element on the ultimate strength of the steel shear wall were presented.
