摘要

Concrete-filled composite shear walls (CF-CSWs), consisting of steel plates, a concrete core, and transverse connectors, are advanced lateral load–resisting systems offering high stiffness, strength, and ductility. These attributes make them ideal for structural cores in high-rise buildings, providing excellent load–bearing capacity under complex loading while reducing construction costs and time. Despite extensive experimental and numerical research, a holistic understanding of their load–bearing mechanisms and performance under diverse loading scenarios remains incomplete. This review synthesizes foundational and recent studies on CF-CSW stability and seismic behavior, analyzing their response to in-plane and out-of-plane loads. It evaluates key design parameters—steel plate thickness, connector spacing, wall aspect ratio, and axial load effects—on capacity and ductility. By systematically classifying existing research, this paper identifies critical gaps in experimental, analytical, and numerical approaches, offering insights to refine advanced modeling techniques, optimize experimental methods, and develop robust analytical frameworks. Future research directions and precise design recommendations are proposed to enhance CF-CSW applications in critical infrastructure.
