Abstract
The present study established a numerical investigation on the behavior of concrete filled steel tube reinforced concrete (CFSTRC) columns under combined loading and two-opposite-side fire. The FEA model was verified by the experimental results of CFST columns subjected to non-uniform fire. The comparison demonstrated an acceptable accuracy for the proposed FEA model. Afterwards, the FEA model was used to analyze the temperature distribution and failure modes of CFSTRC columns subjected to two-opposite-side fire, the influence of fire surface on the fire resistance of the column was also analyzed. The results show that the temperature distribution of the column section is biaxial symmetry, the highest temperature appears at the intersection of the fire surface and the symmetry axis, and the lowest temperature appears at the center of the columns; the load ratios and fire surface have a great influence on the mechanical property of the columns subjected two-opposite-side fire.
