Research on Hysteretic Performance of Perforated Double Steel Plate Shear Walls with Tube Stiffeners
摘要
Abstract
To enhance the hysteresis behavior of steel plate shear walls(SPSWs)and enable them to effectively dissipate energy,a novel design incorporating perforated double steel plates with tube stiffeners is introduced.Finite element models of seven distinct SPSW configurations,including the proposed design,were developed using ABAQUS software.Comparative assessments were conducted to evaluate the failure modes,hysteretic performance,structural strength,stiffness,and energy dissipation capabilities of the various SPSW configurations.The findings indicate that the perforated double steel plate shear wall with tube stiffeners exhibits a high load carrying capacity and favorable hysteretic performance compared to a wall with the same total thickness of steel plate.The incorporation of steel tubes as stiffeners between the wall panels enhances buckling restraint and reduces out-of-plane deformation through strategic placement.Additionally,this design approach mitigates the loss of load-carrying capacity,strength,and stiffness resulting from pre-perforation in the wall panels.The utilization of square or round steel tubes as stiffening elements minimally impacts the load-carrying capacity of the wall.However,square steel tubes exhibit superior buckling restraint and energy dissipation capabilities.Optimal performance is achieved when employing square steel tubes as stiffeners in perforated double steel plate shear walls.关键词
