[en] This report presents the results of the numerical simulations performed by University of Liege in the framework of work package 6 of the FICEB project financed by the Research Fund for Coal and Steel. A full scale fire test was performed in Ulster on February 27th 2010 on a composite floor for analysing the behaviour of long cellular steel beams in a complete compartment office in building structure under realistic fire conditions. The aim was to study the possibility of tensile membrane action to develop when the unprotected steel beams in the central part of the floor are made of cellular beams. Predictive numerical simulations of the test have been performed with the software SAFIR in order to define the appropriate structure to be used for the full scale fire test. As predicted, the structure was able to withstand the test without collapse. After the test, the results of the predictive simulations have been compared to the measured results, showing relatively good agreement.
