Concrete filled steel tube (CFST) have been used in the practice of civil engineering under the pile, columns and fill the docks. As Compare to conventional steel and reinforced concrete components, there are several advantages of CFST. This article presents an analytical modelling for concrete filled steel (CFST) tube section under concentric axial compression. Curly, the main objective of this study to evaluate the effect on buckle load for various geometric of the CFST model condition Finite element model is validated by comparing its results with those included in the experimental study of the researcher. Three Dimensions Non-Linear finite element analysis of the axial compression process is performed using commercial software ABAQUS v6.14. The Results of various models are compared.
