This paper aims to report the experimental study on the axial compressive behavior of tubular stub columns filled with variable concrete strength(fcm=500, 700, 1.000kgf/cm²). Thirty-two specimens were tested to investigate the relationship between concrete strength and the ultimate strength of stub column. The effects of inner concrete on the failure mode, the ultimate strength, initial stiffness and deformation capacity were discussed. Also this paper presents experimental results on the strength and deformation of concrete-filled steel stub columns. Because the strength of concrete filled into the hollow tube was limited less than 500kgf/cm² in Korean standard. From this experimental study, it was found that the axial strength of CFT column was not proportioned increased with the compressive strength of concrete. Both circular and square stub column specimens filled with the compressive strength of 1000kgf/cm² concrete belonged to the failure mode 6 having a steeply decline curve after reaching the maximum load. Therefore, this results can make a contribution to the development of design standard.
