摘要：
To investigate fire-resistance behaviors of rectangular section stainless steel beams with three faces exposed to fire, fire resistance analysis models were established based on existing experiment data, and numerical simulation analysis was conducted. Comparison between the finite element calculation results and the experiment results verified the accuracy of the finite element models. On this basis, parametric analysis was carried out on the fire resistance behaviors of rectangular section stainless steel beams with three faces exposed to fire, with a focus on the influences of the section factor on the temperature distribution, mid-span vertical deformations and critical temperatures. Finally, the formula for the bearing capacity of the rectangular section stainless steel beams with three faces exposed to fire was fitted, providing important references for engineering designs of stainless steel structures in the future.
