Abstract
The results of a numerical study on the fire resistance of the joint between the steel beams, as well as the concrete-filled steel tube column (CFSTC) are provided utilizing the ABAQUS program. The analytical approach has been implemented, which comprises three steps of the sequential analysis, including fire analysis and heat transfer analysis, in addition to stress analysis for predicting the joint’s behavior under a fire loading. They include models of the nonlinear 3D finite element of heat transfer, together with stress analysis. These illustrative models were validated by conducting a comparison between the data of the numerical output with the current experimental results in the literature. This test involves the reverse channel test, i.e., the joint’s test against a fire. The conducted test is among different tests of fire; 10 tests that are available in the literature. The results showed good agreement when the numerical results were compared to the experimental results. Consequently, the models of the finite element can predict the joint’s behavior under a fire loading.
