Systematic experimental studies were performed for the purpose of obtaining the material properties of cold-formed sorbite stainless steel and the mechanical parameters of plug-pin joint. As a new type of material, the scaffold made of sorbite stainless steel has the advantages of convenient construction, high strength and stainless steel. The static tensile tests for S500 sorbite stainless steel investigating the material characteristics of plug-pin joint were carried out. The bending moment, the compressive force, the tensile force and the shear force were applied to the joint respectively. To get the failure modes and moment-rotation (or load-displacement) curves, the joint behavior, including the semi-rigidity between the ledger and the standard, compression and shear of the standard, and the tension of the ledger joint were studied. The result can determine the load-bearing capacity and the performance of the joint. The joint stiffness was determined according to different methods and four models were proposed to describe the bending behavior. By analyzing the different modes of joint failure, the weak part can be determined to provide basis for actual joint design.
