Generally, thin plate shear walls used, but it shows buckling at small loads which results in highly pinched hysteretic behaviour. In order to reduce buckling, constrained ring holes are provided in steel plate. It also uses simple shear beam-column connections. Ring like cut-outs elongate into an ellipse when the shear plate is loaded laterally. The transverse and longitudinal deformations of a circular ring that is stretched into an ellipse are nearly equal. When the rings are provided in the direction perpendicular to the tension diagonal, the slack in the compression diagonal direction will be removed. This reduces buckling. It is more economic, since it requires less steel and no moment connections between beams and columns. It will reduce the pinching in hysteresis loop and provides comparatively good strength and stiffness compared to thin unstiffenedsteel plate shear wall. The present study deals with the buckling and seismic behaviour of steel plate shear wall with ring cut-outs by considering various input parameters like configuration of cut-outs and thickness of web plate.
