Firstly, four specimens 1/8 of the prototype column are fabricated and tested. In this paper, the hysteretic loops are analyzed just for two specimens, namely tube 1 and tube 3. Then the skeleton curves and hysteretic loops of TRCC are simulated by FEM programming ABAQUS. With suitable selection of the constitutive models for concrete and their parameters, the FEM models can capture the main features of TRCC subjected to monotonic and cyclic loading. Finally, based on the numerical results, the influence of axial compression ratio on the ultimate load is studied. It is confirmed that increasing axial compression ratio is adverse to the seismic performance of TRCC. Both the experimental and numerical results show that TRCC exhibit a moderate ability of energy dissipation.
