The application of Concrete-filled square steel tubular column in structural engineering is more and more widely. In order to improve the confinement of concrete core, the configuration of concrete-filled square steel tube strengthened by internal transverse stiffened bars is proposed. This paper employs a experimental research on concrete-filled square steel tube strengthened by internal transverse stiffened bars under axial compression and the influencing factors of bearing capacity such as diameter and spacing of steel bars is analyzed. The results shows that its axial load capacity is increased 2.3%~13.1% than that of ordinary concrete-filled square steel tubular column, spacing changes to improve the bearing capacity of concrete filled square steel tubular column strengthened by transverse stiffened bars is more effective than the increase in stiffened bars diameter.
