The height to width ratio for the specimens is 1.5, and the axial compression ratio is 0.5. The test results show that embedded steel shapes and steel plate can work together with the reinforced concrete. The steel plate-concrete composite shear walls with four edges welded have much higher strength, and their ductility is almost equal to or slightly higher than that of reinforced concrete wall. The shear strength of the composite wall using connecting plate depends on the connecting strength, and the ductility of these types of walls is better. Based on the superposition principle, the calculation formula of the steel plate-concrete composite wall shear strength is suggested, from which the calculated results are quite consistent with the experimental data, and has adequate safety degree as well. The shear force limitation for steel plate-concrete composite wall section is also suggested.Keywords:steel plate-concrete composite wall; shear strength; small shear span ratio; ductility; limitation作者簡介：孫建超，高級工程師，一級注冊結(jié)構(gòu)工程師，Email:sunjch2008@126.com。
