This study investigated the comparison of circular and rectangular concrete filled steel tube (CFST) columns of hot rolled and cold rolled-light gauge columns using the Finite element analysis method. The ultimate load capacity, axial deformation, and stress-strain patterns were compared and discussed for both types of columns. ABAQUS software is used to study the behavior of both types of composite columns by the Finite Element Method (FEM) under axial loading. The major variable considered for the experiment is the thickness of the steel. The thickness of hot rolled and cold rolled light gauge steel is 5.2 mm and 2 mm respectively. It is one circular column constructed with hot rolled steel and the other with cold rolled steel type infilled with M25 grade concrete, which is similar to the same construction for the rectangular type and both simulated in the ABAQUS. This study revealed that light-gauge steel composite columns showed greater yield strength in terms of load to thickness ratio compared to hot-rolled regular steel composite columns. The ultimate axial load with respect to the failure mode is compared to the varied geometric and material properties of the CFST column. The behavior of the column’s load-deformation is tabulated and depicted in the graphs.
