“…Theoretical and numerical analyses were performed for trapezoidal and sinusoidal CSPSWs to analyze their elastic and inelastic shear buckling behaviors. [1][2][3][4][5] Dou et al 6,7 and Qiu et al 8 investigated the shear resistance and post-buckling behavior of trapezoidal and sinusoidal CSPSWs by extensive numerical analyses. Berman et al 9 investigated the performance of trapezoidal corrugated panels experimentally, and results showed that CSPSWs exhibited satisfactory ductility and energy dissipation capacity.…”

“…According to the discussion above, CSPSWs are expected to improve their lateral load-bearing and energydissipating capacities by increasing their shear buckling strength. Jin et al 2,15 proposed nonbuckling CSPSWs that no evident buckling would be observed on corrugated panels under a drift ratio of 1/50. There were strict restrictions on the thicknesses, corrugation amplitudes, and width-to-height ratios of corrugated steel plates for nonbuckling CSPSWs.…”

Corrugated steel plate shear walls (CSPSWs) can be applied to high‐rise building structures to serve as lateral load‐bearing and energy‐dissipating members. Arranging stiffeners on corrugated steel plates shows substantial potential to further improve the seismic performance of ordinary CSPSWs. This study experimentally and numerically investigated the hysteretic behavior of unstiffened and stiffened CSPSWs. Cyclic quasi‐static tests were conducted on four, 1/2‐scale, two‐story, single‐bay specimens with different corrugation orientations, including two specimens with unstiffened corrugated steel plates and two specimens installed with stiffened corrugated steel plates equipped with two pairs of stiffeners. According to the hysteretic curves of different specimens, the effects of corrugation orientations and arrangement of stiffeners were revealed in terms of the skeleton curves, energy‐dissipating capacity, and stiffness degradation. Then, finite element (FE) models, which were applied to gain a deeper understanding of the experimental results, were established, and validated against the test results. This study demonstrated that the arrangement of stiffeners was effective in improving the seismic performance of CSPSWs regarding the ultimate shear strength and energy‐dissipating capacity, while the influence of corrugation orientations on the performance of the specimens involved in this study could be ignored.

Stiffened corrugated steel plate shear walls (SCSPSWs) are novel seismic‐resistant members used in medium‐ and high‐rise building structures, in which a stiffener system is applied on the corrugated steel plate to restrain its out‐of‐plane buckling deformation. In this study, experimental and numerical investigations were conducted on the SCSPSW. Using a four‐bar linkage loading device, seven specimens were tested under low‐circle cyclic shear loads, including six SCSPSW specimens and one unstiffened corrugated steel plate shear wall (CSPSW) specimen. Five sets of comparisons were established among the seven specimens to study the effects of the sub‐panel aspect ratio, stiffener torsional constraint, plate‐stiffener connection method, bolt layout scheme and bolt strength on the seismic behavior of the SCSPSW. Desirable shear resistance capacities, ductility, and energy‐dissipating capacities were exhibited through the hysteretic curves. The test results confirmed the validity of existing design formulas for the ultimate shear resistance of the SCSPSW. Then, finite element (FE) models were developed and validated against the test results, indicating the accuracy of the models in simulating the seismic behavior of SCSPSWs. Based on the validated FE models, the internal tensile and shear forces of the connecting bolts were obtained. Accordingly, the development law of the bolt internal force was analyzed in detail. A calculation procedure for predicting the bolt internal forces was proposed and proved to be reasonable. Finally, the effect of stiffener strength on shear resistance and post‐buckling behavior of the SCSPSW was investigated numerically. The research results of this study can provide some references for the engineering practice of the SCSPSW.

“…To resist such imposed forces, the boundary columns require relatively heavy sections, which makes them expensive to fabricate [3,4]. Several methods have been established to overcome the weaknesses of the SPSW, which include: using stiffeners for SPSW [5][6][7]; composited SPSW with a) Fiber Reinforced Polymer (FRP) [8,9], b) concrete layers [10,11]; utilizing Low Yield Point steel (LYP) for main infill plate [12,13], utilizing semi-supported SPSW [14,15]; utilizing corrugated SPSW for infill plate [16,17].…”

Fire can be an adverse event with tangible costs for property and human life. In addition to its physical costs, fire has a range of obvious adverse consequences on the environment. One of the fire’s adverse outcomes is its effect on the structures. Corrugated Steel Plate Shear Walls (SPSWs) are environmentally friendly since they can be manufactured in the factory, reducing the environmental disturbance around the construction site, and also, they can be easily dismounted and recycled. In this paper, the effect of fire on the behavior of corrugated SPSWs was investigated numerically and parametrically. In so doing, the hysteresis of the system before (at the ambient temperature) and after applying the fire was investigated. For the parametrical study, the effect of the thickness (t) and the length-to-height ratio (ω=L/H) of the infill plate were investigated on the ultimate strength, stiffness, and yielding of the corrugated SPSW system. The finite element (FE) results showed that by increasing the thickness as well as the length-to-height ratio, the behavior of the corrugated SPSWs was improved. Also, the results indicated that fire affects the ultimate strength, yielding over the wall and hysteresis curve; additionally, the stiffness is affected by the fire. It was proposed to account for the fire by applying the reduction factor of 0.4 to the ultimate strength.
