Resumo: Fire is an extreme action, to which a steel structure may be submitted, and therefore, must be designed to resist. Traditionally, the fire resistance of structural steel beams has been determined in standard fire tests, with the temperature-time curveISO834representing more severe heating conditions compared to that which occurs in many typical natural fire compartments.Thereforeto design a steelstructure safely and economically, it is necessary to calculate temperature distribution in steel beamsunder natural fire. In this paper, the temperature profiles in a steel beams under natural fire arestudied first, using spread-sheets written by authorsand compared to standard fire. Secondly, twoCardington compartment corner office tests are highlighted,and analysis of primary and secondary steel beamsis presented.Simple theoretical natural fire models based on Eurocode EN 1991-1-2 parametric compartment fire are used and a comparison is made using the experimental results from tests conducted at Cardington research centre, UK. Compartment temperatures and cross-section temperature distribution respectively demonstrates that analytical fire models and experimental results are in good agreement in the case of timber cribs fire load.
