5. Conclusions After modeling, finite element analysis, mesh convergence study, and benchmarking with numerical testing, several conclusions that can be drawn are presented as follows:  Based on each calculation approach, the obtained results are quite identical. There are differences in values ​ at specific points in the ANSYS and VULCAN software due to the lack of detailed input of the material properties.  During the heating process, the structure will experience an axial tensile load along with the addition of deformation. During the cooling process, the structure will try to return to its original shape and cause the axial load to become a compressive axial load.  For a total of 600 mesh elements, the values converge with an error value of 0.6%. Therefore, it can be concluded that the number of selected mesh elements is the most recommended one for further studies regarding the fire structure analysis. For further research, it is expected, the current methodology of fire-structure analysis can be projected to be applied to calculate stress and other structural behaviors in parametric studies of various critical structures and infrastructures with variation on fire configuration and geometrical model based on an actual compartment or structural frame so that mechanical failure due to fire can be identified.
