| dc.description.abstract | The main goal of this paper is to calculate the temperature distribution in four different hot-rolled steel profiles (IPE, HEM, L and UAP), during a thermal and transient process due an accidental fire situation. This work presents the lumped capacitance method, according to the section factors effect, and compares all results with the finite element method, using Ansys® numerical program. The basis of the lumped capacitance method is that temperature of the solid body is uniform at any given time instant during heat transient process. This methodology is compared with the numerical results and allows the calculation of the temperature evolution in steel profiles under fire, like an easy way to follow. The results comparison allows to verify an agreement between the used methodologies. This find enabled to conclude that the lumped capacitance method is accurate and could be easily applied. This method allows to calculate a constant temperature distribution for any profile, at any time instant. It was also intended to understand the relationship between the increase in the cross-section and the temperature difference in the profiles. In the studied profiles ranges with the larger cross-section, a lower temperature field was obtained. As conclusion, members with low section factors will heat up more slowly. | pt_PT |
