Behavioral Improvement of Steel Plate Shear Walls with Rectangular Openings
This research investigates the behavior of steel plate shear walls with a rectangular opening. A rectangular opening on the infill plate is often required to accommodate door or window or other utility system to pass through the shear wall. However, steel plate shear walls with rectangular openings are not adequately studied, and there are not many design provisions available for them. In this research, finite-element analyses were carried out on unstiffened models with different sizes of a rectangular opening. A decrease in the shear strength of the panel was observed in all models. Large out-of-plane deformations were also observed around the opening due to the early buckling of the infill plate. As a solution to this problem, stiffeners were attached to the models and the models were analyzed again. Various arrangements of stiffeners were considered for the models and the effectiveness of each arrangement on preventing the deformation of the opening was studied. The results showed that attaching stiffeners to the plate is an effective method to prevent the out-of-plane deformation of the opening as well as increase the shear strength of the panel. Based on the obtained results, recommendations for the best stiffener arrangement that is most effective in preventing the overall deformation around the opening are presented.
