Investigating Seismic Behavior and Analyzing the Nonlinear Behavior of the Corrugated and Flat Steel Shear Walls

The use of steel shear walls has always drawn much attention due to their creation of high hardness and strength in metal frames. The present study examines the use of triangular corrugated sheets compared to fat sheets. Although its more expensive in contrast to the flat sheets, the triangular corrugated sheets feature more resistance to buckling and prevent severe stress to concentrate on the frame. Using ABAQUS and laboratory validation results for three flat and corrugated shear walls, the remarkable ability of ABAQUS has been proved again herein for the analysis of steel shear walls. The present study compares sixteen shear wall models with different lengths and amplitudes. The results indicated that the increase in the length and decrease in the corrugation amplitude caused increases in the elastic hardness of the frame. Sheets with 10-centimeter corrugation amplitude and 30-centimeter length outperformed the others and featured buckling resistance of about twice as much as the flat sheets. A comparison of the horizontal and vertical triangular corrugated sheets reflects the idea that the use of column-parallel corrugations can increase the frame’s strength. In this research paper, 24 frames with flat and corrugated walls reaching thicknesses of 4mm, 5mm, and 6mm have also been examined in 1-, 2-, 4- and 8-story buildings. The results indicated that the frames made of corrugated sheets behave more favorably compared to the flat sheets and the higher the thickness of the corrugated sheets, the higher the energy dissipation and the higher the frame’s strength will increased.
