Starting from the radiant intensities provided by previous computational fluid dynamic simulations performed in FDS for various design fire scenarios, the thermo-mechanical response of a steel-framed structure of a production department of an industrial plant was modelled.
In particular, the global analysis of the structure was carried out with the SAFIR calculation software, dividing the analysis into two phases: the thermal analysis, to model how the elements heat up when exposed to natural fire, and the structural analysis, to model the global behaviour of the structure taking into account the indirect stresses deriving from the thermal action, also in compliance with the Technical Standards on Constructions.
