Study of Bearing Capacity for Vertical Stiffener Joint with Concrete-Filled Square Steel Tube and Steel Beam

Article Preview

Abstract:

Based on the limit equilibrium method and assumptions of vertical stiffener joint model, the stress mechanism of vertical stiffener joint model is analyzed for concrete-filled square steel tube and steel beam. The formula of bearing capacity for vertical stiffener joint of concrete-filled square steel tube and steel beam is established. The rationality of proposed formula is validated by comparing analytical results with experimental data. Moreover, some factors involved in the proposed bearing capacity formula of connection joints are discussed. The results can provide some theoretical references for the study of bearing capacity of annular plate joint.
