Section performance analysis of vertical corrugated steel plate-reinforced concrete composite shear walls

A vertical corrugated steel plate embedded in steel-reinforced concrete composite shear wall demonstrates good seismic performance while adapting well to the section type and material of load-bearing members, thus demonstrating promising application prospects. This study analyses the stress distribution of a vertical corrugated steel plate-reinforced concrete composite shear wall (SPCWV) section and proposes a theoretical calculation method for the sectional yield, peak, and ultimate state curvatures controlled by the strain of the H-shaped steel section at the boundary element and confined concrete. Furthermore, the proposed method is extended to investigate the influence of structural settings, such as the geometric parameters of the vertical corrugated steel plates, H-shaped steel at the boundary element, and distributed rebars, and material properties, such as concrete and steel strength variations under different vertical loads on the section curvature and curvature ductility. The method is also used to determine the corrugated steel plate content ρcp and H-shaped steel content ρH to more effectively reflect the variations in the geometric parameters of the corrugated steel plate and H-shaped steel. Finally, simplified calculation methods for the yield, peak, and ultimate point curvatures of SPCWV are proposed, and their accuracy and applicability are verified.
