Investigating the behavior of a steel shear wall consisting of a corrugated and flat plate with fully and semi connections to boundary elements

The steel shear wall system has been widely used for decades due to its efficiency. A traditional steel shear wall, without stiffeners, offers advantages such as sufficient strength, stiffness, ductility, and excellent energy dissipation capacity. However, a major issue with this system is the premature buckling of the infill plate, resulting in a slight loss of strength and reduced energy absorption capacity and ductility for the structure. While stiffeners have been suggested to address this problem, their use comes with complications and implementation challenges. One solution to this issue is the utilization of corrugated plates. However, adopting corrugated walls, despite their advantages, can reduce resistance compared to flat steel shear walls. Therefore, a system combining the benefits of flat and corrugated plates is being explored. In this research, the behavior of steel shear walls composed of flat and corrugated plates, with both full and semi-connections to boundary elements such as beams and columns, has been examined using finite element analysis. The findings from these analyses reveal that employing a combined system enhances strength and initial stiffness compared to a flat steel shear wall. Furthermore, the resistance of the combined steel shear walls, particularly those connected to the beam, decreases by 12.8% compared to the overall connection to the boundary elements. Additionally, the resistance of the combined systems connected to the column is 25.2% lower than their counterparts connected to the beam.
