Abstract
The buckling-restrained steel plate shear wall with inclined slots (called Slotted-SPSW), composed of slotted steel plate, frame beams and columns, and out-of-plane constrained concrete panels. Premature failure of boundary frames may lead to insufficient performance of the Slotted-SPSW. To understand the interaction between the slotted steel plate and the boundary frame, the theoretical formula for calculating ultimate load-bearing capacity of the novel Slotted-SPSW is initially provided, and then internal forces in boundary columns are derived through theoretical analysis. Subsequently, a quasi-static experiment on a scale model with a ratio of 1:3 is conducted to examine the mechanical behavior and failure modes of the Slotted-SPSW under lateral forces. Finally, a comparison between the finite element simulation results for the frame columns and slotted steel plate and the experimental results is presented, verifying the accuracy of the theoretical formulas and finite element simulations. The research findings demonstrate that the novel Slotted-SPSW possesses exceptional load-bearing capacity, energy dissipation ability and ductility.
