Experimental Study for the Joints of New Thinwalled Steelconcrete Composite Structure/Zhang Yaochun,  Yu Hongjun,  Cao Baozhu(School of Civil Engineering,Harbin Institute of Technology, Harbin 150090, China)
Abstract:Through the experimental research of ten joints of thinwalled steelconcrete composite structures with different connection forms and loading modes, and two ordinary reinforced concrete joints for the contrast test, the working mechanic and the mechanical property together with the merits and faults of these joints are explored. The test indicates that the joints of the thinwalled steelconcrete composite structures  have better ductility property and enough bearing capacity which can be referred in the actual project.
Keywords:thinwalled steelconcrete composite structure; joint; experimental research; ultimate strength
