Research on the specially-shaped corrugated steel plate shear walls with horizontal corrugation
Abstract A specially shaped corrugated steel shear wall (S-CSSW) system was proposed for the application of steel residential buildings. The proposed shear wall system featured a main shear wall with small section concrete filled steel tube (CFST) boundary columns and horizontally corrugated shear plates and side short pier CSSWs in the perpendicular direction. Quasi-static cyclic tests were performed on the S-CSSWs with and without reinforcing beams to investigate the shear strength, failure modes and hysteretic responses. Finite element simulations were introduced to further study the shear bearing mechanisms of S-CSSWs for a comparison with traditional flat plate shear walls with similar wall configurations. An additional parametric simulation was performed to investigate the influence of the corrugated plate width on failure modes. Results indicated that the proposed S-CSSWs possessed good ductility. Compared with the flat plate shear walls, the proposed shear walls had higher initial stiffness and elastic shear strength. The width of the corrugated shear panels was an important factor influencing the failure modes and lateral bearing abilities and needed to be carefully controlled to avoid early buckling occurring ahead of the shear yielding mode. Some design remarks are concluded regarding the design of the corrugated shear panels and stiffening beams.
Highlights A specially shaped corrugated steel shear wall (S-CSSW) system was proposed. Quasi-static cyclic tests were conducted on two S-CSSW specimens to investigate the shear performance. The proposed S-CSSWs possessed high initial stiffness, elastic shear strength and ductility. Width of corrugated shear panels need to be controlled to ensure the full section shear yielding mode. The involvement of stiffening beams is an efficient measure to the increase shear buckling strength.
