“…Wang et Experimental [8][9][10][11][12][13][14][15][16][17] and numerical analysis [18][19][20][21][22][23] have been conducted on the cyclic and lateral behavior of CoSPSWs and have revealed that the hysteresis curve pinching of flat wall plates could be obviously improved and energy dissipation could be increased accordingly [20,21], and the corrugated wall plates could even achieve shear yielding sometimes, which significantly lowered the anchoring forces on the boundary frame [15]. Furthermore, extended research has been conducted on corrugated steel shear walls with perforations or openings [24][25][26][27], a reduced beam section [28,29], a semi-rigid boundary frame [30], and a low-yield-point steel wall panel [31], as well as on the application of corrugated steel shear walls in a modular structural design [32]. A performance-based seismic design (PBSD) procedure has also been proposed [33], and time-history analyses have revealed that the inter-story drift of the CoSPSW with PBSD distributed more smoothly than the CoSPSW with a traditional design, which helped to avoid weak stories.…”

The corrugated steel plate shear wall (CoSPSW) is a new type of steel plate shear wall, in which corrugated wall plates instead of flat wall plates are adopted. The lateral stiffness and shear buckling capacity of the shear wall system could be significantly enhanced, and then, wall plate buckling under gravity loads would be mitigated. This paper presents a study on the probabilistic assessment of the seismic performance and vulnerability of CoSPSWs using fragility functions. The damage states and corresponding repair states of CoSPSWs were first established from experimental data. Then, incremental dynamic analyses were conducted on the CoSPSW structures. The structural and nonstructural fragility functions were developed, based on which the seismic performance and vulnerability of the CoSPSWs were obtained and compared with the conventional steel plate shear walls (SPSWs). It was shown that for various repair states, the 25th percentile PGA of the CoSPSW was always higher than the SPSWs with the same wall thickness and boundary frame, which indicated that the CoSPSW has a lower damage potential and better seismic performance than the SPSW.

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.

Recently, corrugated steel plate shear walls have been shown to be an efficient lateral force resisting system for building structures. Corrugated plates have higher out-of-plane stiffness and improved buckling stability in comparison with flat plates which result in improved hysteretic behavior. However, the thickness of the corrugated plates may be limited due to the cold-form process restrictions. This paper investigates the cyclic performance of double corrugated steel plate shear walls. One-story single-bay specimen was designed and modelled and parametric studies were performed. The parametric study considered the orientation of corrugated plates (horizontal or vertical), disconnection of infill plates from columns, disconnection of infill plates from each other, infill plate thickness and infill plate aspect ratio on cyclic performance of double corrugated steel plate shear walls. The present study results show that proper selection of the aforementioned parameters can lead to a desirable cyclic performance. In the end, a recommendation for calculating initial stiffness and ultimate strength of double corrugated steel plate shear walls is given.
