To address the issue of out-of-plane buckling in flat steel plate shear walls, this paper proposes a new type of cross-slanted corrugated steel plate shear wall (CCSPW) with enhanced out-of-plane buckling-restrained performance. The study aims to investigate the influence of the corrugation angle on its seismic performance. To this end, three 1/3-scaled CCSPW specimens were designed and manufactured. The experimental study was conducted using the MTS loading system, focusing on various seismic performance indicators, such as initial stiffness, bearing capacity, failure process and form, energy consumption capacity, and ductility under low cyclic loading. The results show that CCSPWs can effectively prevent out-of-plane bulging under low cyclic loading, showcasing excellent lateral bearing capacity. The cross-slanted corrugated steel plates, subject to a joint force of tension and pressure, effectively improve the initial stiffness of specimens. Notably, the CCSPW specimen with an oblique angle of 60° exhibits the greatest initial stiffness. The specimen with an oblique angle of 45° shows a bearing capacity that is 5.5% and 10% higher than those of the other two specimens, along with the highest ductility coefficient and superior ductility. Additionally, the specimen with an oblique angle of 60° displays the largest equivalent viscous damping coefficient, ranging from 2% to 5% higher than those of the other two specimens, indicating excellent energy dissipation capacity.
