Evaluation of Steel Shear Walls Behavior with Sinusoidal and Trapezoidal Corrugated Plates

Abstract

Reinforcement of structures aims to control the input energy of unnatural and natural forces. In the past four decades, steel shear walls are utilized in huge constructions in some seismic countries such as Japan, United States, and Canada to lessen the risk of destructive forces. The steel shear walls are divided into two types: unstiffened and stiffened. In the former, a series of plates (sinusoidal and trapezoidal corrugated) with light thickness are used that have the postbuckling field property under overall buckling. In the latter, steel profile belt series are employed as stiffeners with different arrangement: horizontal, vertical, or diagonal in one side or both sides of wall. In the unstiffened walls, increasing the thickness causes an increase in the wall capacity under large forces in tall structures. In the stiffened walls, joining the stiffeners to the wall is costly and time consuming. The ANSYS software was used to analyze the different models of unstiffened one-story steel walls with sinusoidal and trapezoidal corrugated plates under lateral load. The obtained results demonstrated that, in the walls with the same dimensions, the trapezoidal corrugated plates showed higher ductility and ultimate bearing compared to the sinusoidal corrugated plates.

Innovative hollow columns comprising corrugated plates and ultra high-strength steel tubes

“…The most common profiles used are trapezoidal and sinusoidal. In this research, trapezoidal profile is chosen to be studied as it exhibits more ductility and higher bearing capacity compared to sinusoidal profile [15].…”

Seismic Evaluation of New Steel Infill Panels for Steel Shear Walls

“…To date, several numerical and experimental studies have investigated the behavior of Corrugated Steel Shear Walls (CSSW) with curved and trapezoidal corrugated steel plate under monotonic and cyclic loading. Based on the comparison of the numerical results [4][5][6], trapezoidal CSSWs depicted slightly higher ultimate load, energy dissipation and toughness compared to the curved CSSWs. Furthermore, the connection between thin steel plate and boundary frame is easier for the trapezoidal corrugated plate.…”

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].…”
