Title: Experimental study on seismic performance of trilaterally constrained steel plate composite shear walls
Abstract: A new type of steel plate composite shear wall,assembled by steel plate and precast cement-based concrete plate,is presented in this paper.The steel plate,which is different from normal steel plate shear walls,has trilateral constraints and one elastic restrained side.The precast concrete plate was designed to prevent steel plate from buckling.Six specimens,including three steel plate shear walls and three composite shear walls,with various of width-thickness were tested by jack.The failure mode,shear strength,lateral stiffness,and the buckling mode were investigated by experimental study.The result indicates that width-thickness ratio of steel plate has effect on the shear-carrying capacity and failure mode;small width-thickness ratio of steel plate requires adequate anchorage to prevent failure of boundary;the lateral stiffness of steel plate can be enhanced by the precast concrete plate,and the buckling strength or shear strength of steel plate wall are improved.The material capacity of steel plate can be fully developed with composite buckling-restrained shear wall;the earthquake resistant behavior of the structural system can be enhanced more.
