Experimental and theoretical studies have been carried out to investigate the behavior of elastic-plastic stability of concrete filled steel square tubular columns under compressive force. Two types of test specimens of steel tube columns of STKR400 and concrete filled steel tubular columns were tested under concentric axial compressive force. It is confirmed that the tangent modulus theory predicts not only the buckling strength of steel columns but also that of composite columns, and the superposition method is applicable to predict the buckling strength of composite long columns. The post buckling behavior have been predicted by elastic-plastic analysis under eccentric axial compressive force, assuming that the deflection mode is the half-wave of the sine.
