Popis:	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 objective of this paper is to investigate the behaviour of industrial steel portal frames with haunches in fire situation. The structure is studied using finite element software ANSYS with an uncoupled thermal and mechanical analysis. The inclination angle of the rafter and the haunch’s length for the portal frame are taken as variables. A comparative study of the numerical simulations and the simplified method (R15) show a close agreement between the two analyses according to the failure time. info:eu-repo/semantics/publishedVersion
