Abstract: The concrete filled steel tube nodes of a composite structure in Shenzhen have been studied, and finite element software ANSYS has been used for the seismic performance of them. A proper constitutive relation has been used in the analysis based the target of seismic performance and necessary computational accuracy, and the possible unfavorable conditions of the nodes have been considered. The analysis results show that all of the nodes can meet the seismic performance objectives, the most dangerous parts of the nods are the smallest cross-sectional area. The nodes have maximum Mises stress in steel tube concrete corner portion, and maximum principal compressive stress of concrete appears in the steel flange area. Steel beams are good for the balance of moment, and they should be strengthened.
Keywords: concrete filled steel tube; composite node; finite element
