<p>In this investigation, a corrugated steel shear wall (CSSW)’s reaction encompassing two horizontal and vertical trapezoidal corrugated infill plates called orthogonal double CSSW (ODCSSW) was explored under cyclic loading by a finite element (FE) approach in Abaqus software. Flat steel shear walls (FSSW) and standard single-CSSW and DCSSW with vertical and horizontal orientations were examined to assess the system's efficacy and behavior. Mechanical and geometrical properties of the perimeter elements were identical in all models. The results displayed that DCSSWs provided maximum resistance, initial hardness, and more energy absorption than ordinary double- and single-layer steel shear walls. So, the resistance of double orthogonal walls is at least 7% and a maximum of 35% higher than that of ordinary DCSSWs. Additionally, the difference between orthogonal and single-corrugated walls ranges from 11 to 44%. The increase in energy absorption in ODCSSW varies between 5 and 31% compared to ordinary double-corrugated walls. The results displayed that the resistance and energy dissipation of the ODCSSW are increased with the increasing corrugation angle. So, the ODCSSWs with the corrugation angle of 60° have demonstrated the maximum resistance and energy dissipation.</p>

摘要

In this investigation, a corrugated steel shear wall (CSSW)’s reaction encompassing two horizontal and vertical trapezoidal corrugated infill plates called orthogonal double CSSW (ODCSSW) was explored under cyclic loading by a finite element (FE) approach in Abaqus software. Flat steel shear walls (FSSW) and standard single-CSSW and DCSSW with vertical and horizontal orientations were examined to assess the system's efficacy and behavior. Mechanical and geometrical properties of the perimeter elements were identical in all models. The results displayed that DCSSWs provided maximum resistance, initial hardness, and more energy absorption than ordinary double- and single-layer steel shear walls. So, the resistance of double orthogonal walls is at least 7% and a maximum of 35% higher than that of ordinary DCSSWs. Additionally, the difference between orthogonal and single-corrugated walls ranges from 11 to 44%. The increase in energy absorption in ODCSSW varies between 5 and 31% compared to ordinary double-corrugated walls. The results displayed that the resistance and energy dissipation of the ODCSSW are increased with the increasing corrugation angle. So, the ODCSSWs with the corrugation angle of 60° have demonstrated the maximum resistance and energy dissipation.
