A new type of joint between Concrete-filled Square Steel Tube columns and steel beam is proposed in this paper, and the seismic behavior of this type of joint under low-reversed cyclic loading experiment is researched. Ductility behavior, dissipation of seismic energy of this joint under horizontal, repeat load are analyzed. The experimental results showed that all specimens have good ductility and energy dissipation capacity. The story angle drift ductility ratios are μ=3.23~3.63, and the equivalent viscous damping coefficients are he=0.25~0.35,which meet the needs of the code for seismic design of building.

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.

Square Steel Tube

All-bolted steel beam-to-column connections for concrete-filled square steel tube (CFST) have the advantages of industry manufacture, being constructed quickly and easily concreting. The new design all-bolted connection discussed in this paper has the construction details of Π-shape plate and high strength bolts which connect the steel beam and CFST column. In order to investigate the static performances and failure modes of this new all-bolted connection, a full three-dimension ANSYS finite element (FE) model of the connection subjected to montonic load is built up. The theoretical values and experimental results are very close, that verifies the rationality of the FE models and the analysis method in this research. Further the calculated results demonstrated the new bolted connections belong to typical semi-rigid connection and have the superior static resistance in stiffness, strength, and rotating capacity.
