Performance of steel-plate-reinforced concrete composite walls in tall structures

Steel-plate-reinforced concrete composite walls are now widely used in tall buildings in China, particularly in earthquake zones. This paper presents the features and mechanisms of steel-plate-reinforced concrete walls together with a summary of experimental and finite-element investigations. The results indicate that seismic performance is considerably enhanced by the steel plates, which effectively improve shear resistance and prevent deterioration of concrete in compression compared to conventional reinforced concrete walls. This paper aims to provide a useful design reference for future application of steel-plate-reinforced concrete walls.
