Following Standard for Structural Calculation of Steel Reinforced Concrete Structures, two design formulas for concrete-filled steel tubular (CFT) columns subjected to axial load and bending moment are specified for columns not longer than, as well as columns longer than 12 times depth or diameter of the steel tube section. However, on the other hand, three design formulas for CFT columns subjected to only axial load are shown for columns with l_κ/D &le: 4, 4 < l_κ/D ≤ 12, 12 < l_κ/D proportion category. The former mentioned design formulas are not consistent to the later design formulas. This paper has proposed the design formula 4 < l_κ/D ≤ 12 proportion category for CFT columns subjected to axial load and bending moment, similar as in the case of CFT columns subjected to only axial load.
