The temperature model takes advantage of great possibilities of computational fluid dynamics code Fire Dynamics Simulator. The model is based on an accurate representation of a real fire furnace of fire laboratory PAVUS a.s. located in the Czech Republic. It includes geometry of the real furnace, material properties of the furnace linings, burners, ventilation conditions and also a tested specimen with measurement devices. The model allows controlling of gas temperature and the static over pressure in the volume of the furnace as it is specified in requirements of European standard for fire resistance tests. The paper presents several improvements of the model which lie in an accurate description of physical material properties, usage of a finer mesh density and application of a forced ventilation system. The improved virtual furnace is used to calculate temperature environment around a steel beam. The temperature fields are then passed to thermomechanical model to solve mechanical behavior of the tested element.
