摘要

The enhancement in the nonlinear mechanical behavior of steel shear walls under the effect of perforated trapezoidal corrugated steel plates is addressed herein. The shear wall in conjunction with the trapezoidal plates was simulated with a 1/2 geometric scale in ABAQUS subjected to lateral loads through a Rik’s procedure. Each model was first exposed to opening excised at the middle and corner doors as well as at the window places to evaluate the reduction level in the stress bearing capacity. Then, stiffeners in the form of box and plate sections were utilized in each case, where the latter proved more efficacious in terms of stress level and energy absorption increase. The effect of stiffness, reflected through that of the thickness of stiffeners, was then evaluated in every configuration. This effect was quantified through the limit load and energy absorption parameter, which was observed to be significant in all cases. The two parameters reached, respectively, 106 and 166% for the middle door, 100 and 151% for the corner door, and 102 and 132% for the window openings (with respect to those for the solid wall). Ultimately, the optimization factor was evaluated, representing the ratio of the stiffener cross section to the opening area that corresponds to strength and energy absorption equivalent with those in the solid wall.
