Abstract:In order to address the problem that flat steel plate shear walls are prone to out-of-face buckling, a new type of cross-slanted corrugated steel plate shear wall (CCSPW) with self-protection against out-of-face buckling is proposed. In order to study the influence of corrugation angle on its seismic performance, three 1/3 scaled CCSPW specimens were designed and manufactured, and the experimental study was conducted through the MTS loading system. Meanwhile, the seismic performance indicators, such as initial stiffness, bearing capacity, failure process and damage form, energy consumption capacity, and ductility, were analyzed under the low cycle of repeated loads. The study shows that under the action of low cycle repeated loading, CCSPW can effectively prevent the phenomenon of outward bulging and has excellent lateral bearing capacity; cross-slanted corrugated steel plate with one tensile and one compressive joint force effectively improves the initial stiffness of the specimen. Among them, the CCSPW specimen with an oblique angle of 60° has the greatest initial stiffness. The CCSPW specimen with an oblique angle of 45° has a bearing capacity that is 5.5% and 10% higher than that of the other two specimens, and has the largest ductility coefficient and the best ductility. The CCSPW specimen with an oblique angle of 60° has the largest equivalent viscous damping coefficient, which is 2-5% higher than that of the other two specimens, and has a more excellent energy dissipation capacity is excellent.
