Experimental Study on Seismic Behavior of High Strength RC Shear Wall Incorporated with Formed Steel

Three kinds of 1 /3 scale model of shear walls,including normal high strength concrete shear wall(SW),SW incorporated with steel frame(TSW),and TSW combined with braces of truss constituted by bars(TSW-BT),were tested to evaluate their seismic behaviors.Meanwhile,their characteristics such as bearing capacity,stiffness and attenuation,ductility,hysteretic property and failure phenomena were analyzed and discussed.In addition,comparisons between seismic behaviors of SW,TSW,TSW-BT and normal strength shear wall were carried out.It is shown that the proposed shear walls share good performance,and most of their properties related to seismic behavior are superior to normal strength shear wall.At last,the bearing capacity of this kind shear wall is calculated,which result agrees quite well with the result of the experiment.
