Structural Performance of corrugated steel plate shear walls

- Corrugated Steel Plate Shear Walls (CoSW) represent a groundbreaking advancement in structural engineering, providing exceptional seismic resilience, energy dissipation, and lateral stiffness compared to traditional flat steel plate shear walls. This paper offers a comprehensive review of CoSW performance under various conditions, including cyclic and seismic loads, with a focus on enhancing geometric configurations and reinforcement techniques. Key innovations such as enhanced corrugation angles, stiffener integration, and strategically designed openings are discussed. Recent progress in computational modeling and experimental validation has further refined design methodologies, ensuring their practical applicability. The review highlights that critical parameters such as corrugation depth, angle, and plate thickness significantly influence structural stiffness, ductility, and buckling resistance. Additionally, the use of stiffeners and optimally positioned openings enhances energy dissipation while minimizing material consumption. Comparative analyses underscore the superior energy absorption and seismic durability of CoSW compared to flat plate systems. The study also emphasizes the importance of enhancing geometric configurations and incorporating advanced reinforcement techniques to maximize seismic performance. Future research directions are outlined, including the exploration of novel materials, composite structures, and refined design codes to address evolving engineering challenges. This review provides a valuable resource for engineers and researchers seeking to develop resilient, cost-effective shear wall systems for modern infrastructure.
