dc.description.abstract	To protect human lives and prevent against failure of structures, the collapse of industrial buildings under fire should always occur inward with a minimum failure time. The main objective of this study is to investigate the behaviour of industrial structures with steel portal frames under the effect of fire. In order to achieve this goal, numerical simulations on portal frames with haunches at the ends of the rafters are conducted using finite element software ANSYS. The structures are studied with decoupled thermal and mechanical analyses. For this purpose, geometric and material nonlinearities are taken into account in the analysis using the standard ISO 834 as the fire model. The parametric study is carried out taking into account the parameters influencing the time resistance and the failure modes such as fire scenarios, length of haunches and geometrical dimensions of the portal frames. The comparison results with the simple calculation method R15, in term of time resistance, show a close agreement.	pt_PT
