“…Several kinds of research have shown that using stiffened and unstiffened steel plates can affect the load capacity, ductility, and energy dissipation capacity of the steel walls [1][2][3][4][5][6][7][8][9][10][11][12]. Using corrugated steel plates, in the shape of trapezoids, as stiffened infilled steel plates has been of interest to researchers [13][14][15][16][17][18][19][20][21][22][23][24][25][26]. The influence of different parameters such as corrugation shape, corrugation angle, and opening size, and position on the behavior of the corrugated steel shear walls (CSSW) have been investigated through several experimental and numerical studies.…”

“…Following the experimental work done by Emami et al [13], finite element analysis (FEA) studies were conducted to investigate the cyclic behavior of CSSWs with various corrugation angles and the thickness of the horizontally corrugated infilled plate [17,18,21]. The FEA results of CSSWs with corrugation angles of 30, 45, 60, and 90 showed that increasing corrugation angle enhanced the energy dissipation and cyclic behavior of the CSSWs.…”

“…They concluded that the energy dissipation capacity of the CSPSW was higher than that of a flat steel plate shear wall. Kalali et al (2015) have examined the hysteresis performance of the corrugated steel plate shear wall using finite element analysis. They showed that to achieve optimal performance, they should appropriately select the geometric parameters of the shear wall.…”

The Wall–Frame Interaction Effect in Corrugated Steel Plate Shear Walls Systems

The corrugated steel plate shear wall (CSPSW) system is a lateral force-resisting system, about which many studies have been carried out in recent years. In the present study, the behavior of this system is investigated by pushover analysis. For this purpose, twenty CSPSWs structures are designed with width-to-height ratio (L/H) of 2.5, 2, 1.4, and 0.85, and the number of floors 1, 2, 4, 6, and 10 were designed and analyzed using the ABAQUS finite element software package. The results of this study show that the initial stiffness of CSPSWs is high and reaches its ultimate capacity at a thrust ratio of 0.1%; on the other hand, after the buckling in the infill plate, the stiffness and base shear of the plate shear wall (PSW) significantly decreases. Also, the results show that the infill plate tolerates a higher percentage of shear force before the buckling of the plate, but after buckling, the frame tolerates a higher percentage of the shear force. In multi-story structures, the boundary frame with shear performance in the lower floors has a more effective role in bearing shear force. Moreover, in the present study, an equation is presented for calculating the tension field inclination angle. According to the equation, the tension field inclination angle depends only on the PSW aspect ratio. Finally, a method is presented for estimating the uniform force-displacement curve of the single-and multi-story CSPSW systems. This method is obtained based on the corrugated plate-frame interaction (PFI) and was confirmed with the force-displacement curve of experimental specimens and numerical models.

“…Kalali et al [20] presented a numerical investigation of the hysteretic performance of SPSWs with trapezoidally corrugated infill plates. Finite element cyclic analyses were conducted on a series of flat-and corrugated-web SPSWs to examine the effects of web-plate thickness, corrugation angle, and number of corrugation half-waves on the hysteretic performance of these systems.…”

Unstiffened steel plate shear walls (SPSWs) have been in use mostly in recent years. In this numerical study, the buckling behavior of a single-storey single-bay unstiffened SPSW with two pinned and rigid beam-column connections under lateral loading is investigated. The SPSW had different wall aspect ratios (L/h=1, 1.5, 2, 2.5, and 3) and infill plate thicknesses (tw= 3, 5, and 7 mm). Their effect on the buckling behavior of SPSW was examined using buckling analysis in ABAQUS software. Results indicated that with the increase of infill plate thickness, the lateral resistance of unstiffened SPSW system increases, but by increasing wall aspect ratio, its resistance decreases. In both connection designs, the model with L/ h=1 (square-shaped model) showed better ductility and higher stiffness and strength in all three thicknesses. Maximum shear stress responses of SPSW models showed that in pinned design with L/h=1, the most change in shear stress values was 8% when infill plate thickness reached from 5 to 7 mm; while for rigid connection, it was reported as 7% when it increased from 3 to 5 mm. This indicates that in rigid connection, increasing the infill plate thickness has less effect on the increase of lateral resistance. By examining the performance of rigid and pinned beam-to-column connections with different wall aspect ratio and infill plate thickness, it was found out that maximum shear stress in rigid connection increased by 11% compared to pin connection. It was concluded that an optimum unstiffened SPSW model had a wall aspect ratio of 1 and infill plate thickness of 7 mm.
