Abstract: The axially compressive bearing capacity may be further enhanced,together with the plasticity and ductility also be improved by setting steel bars into circular concrete-filled steel tube column. Based on the limit equilibrium theory of concrete-filled steel tube column,the axially compressive static tests of 38 reinforced concretefilled steel tube short column specimens were carried out,in order to explore their bearing mechanism and failure modes. Some factors influencing the axial load-bearing capacity of the specimens are analyzed. The method of calculating the axial load-bearing capacity for this kind of short column is studied to provide a reference for the subsequent studies and the revision of correlative standards.
