conducted a numerical study to compare the monotonic behaviors of FSPSW and CSPSW with an opening. Emami and Mofid’s subsequent numerical study on corrugated SPSWs pointed to the conducive role of corrugated plates in improving the steel shear wall performance. The results illustrated that CSPSWs exhibited considerably less pinching in hysteresis loops than FSPSWs because of the greater out-of-plane stiffness and buckling strength of corrugated plates, compared to flat plates. The corrugated plates were placed both horizontally and vertically. made a comparison between Corrugated Steel Plate Shear Walls (CSPSWs) and Flat Steel Plate Shear Walls (FSPSWs) in terms of cyclic performances.
As demonstrated by the results, the corrugated specimens suffered a quick loss of strength due to fractures of the infill plate at repeated local buckling locations. The corrugated infill plates were oriented at 45 degrees.
Berman and Bruneau scrutinized 3 light-gauge flat and corrugated SPSWs. In recent years, researchers have evaluated the possible uses of corrugated plates as SPSW infill plates. However, unstiffened SPSWs have substantial pinching in hysteresis loops owing to the diagonal tension field effect. Past research on SPSWs without stiffener revealed that the postbuckling strength and ductility of infill plates could be considerable. Unstiffened SPSWs are of less buckling strength and facilitate shear buckling and the development of diagonal tension field in the panel. However, their fabrication is more expensive and time-consuming because of thin plate welding. Stiffened SPSWs enjoy greater initial stiffness, higher shear strength, and larger ductility than unstiffened ones. SPSWs are either stiffened and unstiffened in type.
Steel Plate Shear Walls (SPSWs) are frequently employed as lateral force-resisting systems in building structures owing to their high stiffness, strength, and ductility. Finally, an analytical method was proposed for calculating the ultimate shear strength of beam-only-connected CSPSWs. The obtained results indicated that selecting the right geometrical parameters could yield a desirable cyclic performance. Noteworthy responses were ultimate strength, initial stiffness, energy dissipation capacity, and force-deformation relationship. Parametric studies have targeted CSPSWs with different geometric variables, including orientation, thickness, and aspect ratio of the infill plate. The design of a one-story single-bay specimen was done and its finite element model was developed. The current study explores the cyclic performance of CSPSWs with beam-only-connected infill plates. But, detaching the infill plate from columns and connecting it to the beams only is assumed here as a method for reducing column demands. In ordinary Steel Plate Shear Walls (SPSWs), infill plates are fixed to beams and columns. Corrugated plates are characterized by greater out-of-plane stiffness and buckling stability than flat plates, ensuring their enhanced hysteretic behavior. Lately, Corrugated Steel Plate Shear Walls (CSPSWs) have gained significance and reputation for being effective lateral force-resisting systems.
