Abstract:An analytical model has been developed for the axial load-bending moment (P-M) interactions of self-consolidating concrete (SCC) columns reinforced with steel tubes. The developed analytical model takes into account the contributions of the steel tubes, unconfined concrete cover, confined concrete core, and confined concrete inside the steel tube. Results of the analytical model were compared with the experimental investigation results of 16 SCC column specimens. The results of the analytical model have been found in good agreement with the experimental results. A parametric study was conducted to investigate the influences of different parameters on P-M interactions of the SCC columns reinforced with steel tubes. It was found that the compressive strength of concrete significantly influenced the maximum axial load of the SCC columns under concentric and eccentric axial loads, while the tensile strength of longitudinal steel tubes significantly influenced the maximum bending moment of SCC columns under flexural load.
