Tall structures are built in large numbers worldwide to satisfy the demands of the urban population. Composite columns like CFST (single and double skin) offer many structural benefits in which the steel and concrete are mutually benefitted, as the steel gives confinement to concrete and the concrete in turn restricts and modifies the buckling of steel tube. Recently developed concrete-filled double-skin steel tubes (CFDST) are recognized for superior ductility and energy absorption capabilities. The present study aims to identify the structural behavior of CFST and CFDST columns under axial compression. Along with this, other objective of the study is to distinguish the best composite column to utilize in construction. The slenderness ratio (L/D), width-to-thickness (b/t) ratio, segment shape, concrete grade, and steel yielding strength are the critical parameters considered for evaluating the axial compressive behavior of CFST (single and double skin) columns. It is discovered that the thickness and diameter of CFSTs can be reduced up to a certain level for D/t and L/D ratios, and also the axial load capacity as well as stiffness of CFST (single and double skin) columns reduces by increasing (D/t) ratio. From the observations, it can be inferred that the load capability of column enhances with higher yield strength of steel.
