Abstract
Lately, Corrugated Steel Plate Shear Walls (CSPSWs) have gained significance and reputation for being effective lateral force-resisting systems. Corrugated plates are characterized by greater out-of-plane stiffness and buckling stability than flat plates, ensuring their enhanced hysteretic behavior. In ordinary Steel Plate Shear Walls (SPSWs), infill plates are fixed to beams and columns. But, detaching the infill plate from columns and connecting it to the beams only is assumed here as a method for reducing column demands. The current study explores the cyclic performance of CSPSWs with beam-only-connected infill plates. The design of a one-story single-bay specimen was done and its finite element model was developed. Parametric studies have targeted CSPSWs with different geometric variables, including orientation, thickness, and aspect ratio of the infill plate. Noteworthy responses were ultimate strength, initial stiffness, energy dissipation capacity, and force-deformation relationship. The obtained results indicated that selecting the right geometrical parameters could yield a desirable cyclic performance. Finally, an analytical method was proposed for calculating the ultimate shear strength of beam-only-connected CSPSWs.
Highlights
Steel Plate Shear Walls (SPSWs) are frequently employed as lateral force-resisting systems in building structures owing to their high stiffness, strength, and ductility
Conclusions e cyclic performance of Corrugated Steel Plate Shear Walls (CSPSWs) with beam-only-connected infill plates was investigated in this study
Responses of interest were force-deformation relationship, initial stiffness, ultimate strength, and energy dissipation capacity. e following conclusions drawn from this study are given as follows: (i) Fully connected horizontal CSPSWs (H-CSPSWs) and vertical CSPSWs (V-CSPSWs) had a similar cyclic performance
Summary
Steel Plate Shear Walls (SPSWs) are frequently employed as lateral force-resisting systems in building structures owing to their high stiffness, strength, and ductility. E 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. In beam-only-connected SPSWs, panels can be fabricated so that there would be a gap between panel edges and the columns, or several panels can be fabricated with a small panel aspect ratio installed parallel to each other in a span In both cases, an opening space may be given adjacent to the column without perforating the infill plate. Subsequent experimental and numerical studies of SPSWs with beam-only-connected infill plates demonstrated that these systems had good initial stiffness and lateral strength and considerable ductility and energy dissipation capacity [30, 31]. The analytical equations employed to measure the ultimate strength of beam-onlyconnected CSPSWs are given
