Abstract
Steel Plate Shear Walls (SPSWs) are utilized for frameworks apposing lateral load for new as well as retrofit developments. For the most part, the shear walls made of thin plates are utilized, however for smaller loads it exhibits buckling resulting in a hysteretic behavior that is highly pinched. So as to lessen the buckling, holes are made in steel plate. Most of the studies provide either a circular or a rectangular hole in the steel plates. Hence we propose an elliptical hole which would improve the performance of the SPSW. This study develops and analyses the performance of a stiffened and unstiffened SPSW model with and without opening in the steel wall.
