Description	Journal: Iop Conference Series: Materials Science and Engineering To further increase the bearing capacity and survivability of reinforced concrete filled steel tube (RCFT) columns, it is offered to supply their concrete core with additional spiral reinforcement. Such reinforcement also has a positive effect on the fire resistance of the columns. The practical use of compressed RCFT elements is restrained by the absence of procedures for determining their bearing capacity. A calculation procedure for determining the strength of short centrally compressed RCFT columns is offered. It is rather easy in terms of application and it allows one to take into account the main features of power resistance of such columns. The results of comparison of the calculated strength with experimental data are presented. The analysis of these results testifies that the accuracy of calculation of RCFT columns strength is sufficient for practice. The offered calculation procedure allows to provide the wider use of RCFT columns in construction practice as heavy loaded bearing elements of buildings and structures. It is recommended to use high-strength longitudinal reinforcement for further increase of the efficiency of these columns.
