Evaluation and comparison of behavior of corrugated steel plate shear walls

Abstract

In this paper, the nonlinear behaviour of steel plate shear walls with corrugated plates under lateral pushover loading conditions in the models' top level has been analytically investigated by the finite element method. The one-storey frames have beams and columns as boundary elements. Steel plate shear walls are simulated using the finite element method, based on the available experimental models in the literature. After calibration of the analytical models, more parameters of steel shear walls with corrugated plates, such as the thickness of the corrugated plate, the stiffness of the boundary elements, the corrugation depth in the corrugated plates and the corrugation length of the infill of the corrugated plates, are investigated. The results of this study have demonstrated that in the wall with constant dimensions, the trapezoidal plates have higher energy dissipation, ductility and ultimate bearing than sinusoidal waves, while decreasing the steel material consumption.

Evaluation and comparison of behavior of corrugated steel plate shear walls 1 INTRODUCTIONSteel shear walls have been used in the construction of high-rise structures in most advanced seismic countries, such as the United States, Japan and Canada, for almost three decades. This system has great advantages compared to other similar systems such as reinforced concrete shear wall and steel braces. The benefits of this system include high ultimate bearing, perfect plasticity, high energy absorption capacity, appropriate stiffness, reduced structural weight, lower foundation construction costs, better quality and high-speed construction. The overall structures of steel shear walls consist of boundary elements such as beams and columns, with infill steel plates in the spaces between them. Steel shear walls can be constructed in two types: unstiffened and stiffened. In unstiff- ened walls, a series of flat plates with light thickness is used for utilizing the post-buckling field under overall buckling. In the second type of wall, a belt series or steel profiles are utilized as stiffeners with different arrangements -horizontal, vertical and diagonal -on one side or both sides of the wall until the energy dissipation, stiffness and ultimate bearing are increased. The first method is completely uneconomical because to improve the hysteresis curve of the walls described it is necessary to increase the thickness of the steel plate until the plate does not buckle before yielding; this increase in thickness will be very significant and uneconomical. The second method, which involves strengthening the plate by a series of stiffeners, is economical and quite effective. By using this method, the hysteresis curves turn from an S-shape to a spindle shape and increase the hysteresis curve area. However, this method, primarily due to welding operations, causes weaknesses of the plate within. It also has higher costs for j...

Cyclic Behavior of New Steel Plate Shear Walls Reinforced with Trapezoidal Corrugated Plates

“…SCPSWs commonly have boundary beams and columns using welded or bolted connections [9][10][11]. Over the past decades, numerous investigations have been conducted on the behavior and design of the SCPSWs [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Among them, the elastic buckling, load resistance, and hysteretic behaviors of SCPSWs under in-plane shear loads were comprehensively evaluated, which can provide valuable references for the design of SCPSWs in practice [8].…”

Experimental Investigation and Numerical Simulation of Corrugated Steel Plate Shear Wall Considering the Gravity Load

“…To assess the matching relationship, the in-plane and out-of-plane stiffness ratio is presented. Yadollahi et al [8] studied the nonlinear behaviour of the sinusoidal and trapezoidal corrugated SPSWs under the lateral pushover loading conditions by numerical simulation. The simulation results found that the property of the trapezoidal CSPSWs is better than sinusoidal CSPSWs.…”

Numerical Parametric Study on the Cyclic Performance of Trapezoidally Corrugated Steel Shear Walls

“…The performance of Steel plate shear walls (SPSW) considerably depends on the infilled steel plate. 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].…”
