In this study, the lateral cyclic response of ten reinforced concrete columns subjected to constant axial load and torsion was experimentally investigated. The parameters of the study were the axial load ratio, torsional rotation/lateral drift ratio, and stirrup spacing. It was observed that torsional moments can significantly reduce the energy dissipation capacity, displacement ductility and plastic rotation capacity while increasing the plastic hinge length. The axial load, torsion and bending interactions computed with models available in the literature were compared with the test results. Using the experimental data, a modification to the existing interaction model was proposed. The plastic rotation capacities of the tested columns were compared with the limits in the Turkish Earthquake Code-2018 and ASCE SEI-2017 neglecting the influence of torsion. Based on the observations, it is found that neglecting torsion induced rotations can be unsafe in performance assessment of reinforced concrete columns.
