Analysis of Prefabricated Steel Plate Shear Wall Based on Seismic Performance

Prefabricated steel plate shear walls have garnered significant attention due to their short construction period, low cost, and excellent seismic performance. This study experimentally and numerically compares the plastic development and failure modes of flat steel plate walls and slotted steel plate walls under cyclic loading. The flat steel plate wall initially yields along the diagonal direction and eventually fails at the upper and lower corners. Both the flat and slotted steel plate walls, exhibit a “breathing effect” and “negative stiffness phenomenon” during loading. The height‐to‐width and height‐to‐thickness ratios significantly influence the initial stiffness and ultimate bearing capacity of both types of walls. Additionally, the slotted parameters affect the performance of the slotted steel plate wall. In terms of energy dissipation, slotted steel plate walls dissipate energy more effectively than flat steel plate walls under small displacements, providing a theoretical basis for designing energy‐dissipating walls for minor earthquakes. This study offers valuable guidelines for optimizing the design and seismic evaluation of prefabricated steel plate shear walls.
