Reinforced concrete girders of curved cable-stayed bridges are subjected to the combined loads of compression-bending-shear-torsion, which can result in complex interaction behaviours. This paper presents an experimental study conducted to understand the behaviours of T-shaped reinforced concrete columns subjected to the combined loads of compression-bending-shear-torsion. The main variables considered in this study are axial pressure ratio and torsional change. The results of tests on twelve reinforced concrete columns subjected to the combined loads are obtained, and the effects of combined loads on the bending strength are discussed. This paper presents the formula established for calculating the bending strength and the diagrams of interaction under the combined loads of compression-bending-shear-torsion. Particularly, the results highlight the turning point from the bending failure to the compression failure, and demonstrate that bending capability increases within the specified range of axial pressure ratio and decreases with the increasing torsion. In addition, this study indicates the importance of considering the effects of compression, shear and torsion on bending strength in the engineering design.
