Zusammenfassung:This article proposed a novel form of composite shear wall composed of a concrete-filled corrugated steel tubular column frame and an infilled corrugated steel plate. This innovative design leverages the excellent out-of-plane stiffness and local-buckling resistance of corrugated steel plates. Quasi-static tests and numerical simulation analysis were conducted on eight composite shear walls. The tests focused on various parameters, including the arrangement of infilled steel plates, the orientation of corrugations, and the presence of openings. The specimens were evaluated for failure modes, hysteresis curves, stiffness degradation, and energy dissipation capacity. The research results indicate that this composite structure exhibited favorable seismic performance, with failure modes observed as yielding of the inner infilled plate and plastic hinge failure of the column bases. The specimens achieved an ultimate drift ratio about 1/50. Additionally, finite element models were employed to analyze the stress distribution within the structure.
