Node rigidity research of concrete filled steel tubular column to steel beam

This article is about the finite element analysis of the connection between steel beam and concrete filled steel tubular, using the structure finite element analysis software ANSYS9.0, It was conducted the study of the mechanical behavior of steel beam to CFST column. Bashed on many experiments ,A finite element study on the joint was made by using ANSYS9.0 .And results were compared to of experiment and the analysis of finite element. Carry on the applicability and evaluation of the model and the analysis to the applicability of this node, It is testified that the non-linear finite element analysis method is correct and feasible, and some advice of improving its structure was put forward.
