Columns made of concrete-filled steel tubes (CFSTs) have been found to improve the weight, stiffness, and ductility of concrete members. However, under axial tension, bending, or torsion, the central portion of the concrete in CFST columns is not completely used. This report presents the numerical results of the study on concrete-filled steel tube and concrete-filled double steel tube columns. The commercial platform ABAQUS is used to do a numerical analysis. Computational techniques are used, and the findings are checked against a literature-based experimental program. The numerical model will diagram the load deflection reaction of the CFST and CFDST specimens. The experimental results in the literature are compared to the column strength expected using finite element analysis and the Eurocode-4 and American Institute of Steel Construction specifications. The D/t ratio has a major effect on the compressive behavior of CFST specimens, according to the results. Concrete cores may also be confiningly confined by CFDST columns, particularly when both the outer and inner tube D/t ratios are small. These findings suggest that a smaller hollow steel tube will comfortably cover the central concrete to create double-skinned concrete-filled steel tube (CFDST) columns. The numerical investigation’s findings are compared in terms of load–deformation trend and ultimate load strength.
