This study presents a Finite Element Analysis modelling (FEA) for Concrete-Filled Steel Circular Tubes (CFSCT) subjected to axial compressive load using the commercial FEA software ABAQUS. A new stress-strain relationship for concrete is established using the experimental data collecting from literature review. Concrete-Damaged Plasticity Model (CDPM) is employed in this study. A new softening regime is proposed for the behavior of confined concrete, and this study also introduces new parameters for constitutive model of concrete when we input into the ABAQUS software. The proposed analysis result is more accurate than the one of previous studies in the case of high-strength concrete or thin-walled steel tubes.
