Abstract：Four composite walls with steel plates and filled concrete are tested under concentric loads with different ratios of distance to thickness. The failure mechanisms of the specimens, load-displacement relations and load-buckling curves of steel plates are analyzed. Experimental results indicate that the buckling of steel plate has little influence on the overall stiffness of specimens. Stud can effectively guarantee the cooperative work between steel plate and concrete. With the ratio of distance to thickness decreasing, both the ultimate bearing capacity of specimen and the buckling strain of the steel plate may be increased. Based on the experimental analysis, the empirical formula for the ultimate bearing capacity and initial stiffness of the composite wall are summarized, and furthermore, a theoretical formula for elastic buckling strain of steel plate is derived.
