Abstract: Based on the appropriate type of the element,material constitutive model,failure criterion and model of cracking and crushing,nonlinear FEA software ANSYS is used to analyse the nonlinear finite elements on the working mechanism of the concrete filled steel tubular column-beam joint with the column tube discontinuous in joint zone.The crack form and mechanical properties of the joint are studied.The calculation results show good agreement between the experimental and analytical results.

Key words: Concrete Filled Steel Tubular(CFST)； column-beam joint； discontinuous tube； finite element analysis；
