Numerical simulation of fire-resistance test of steel beam

Popis výsledku v původním jazyce

The paper describes a virtual furnace for fire-resistance tests following standard fire conditions. The 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 accuracy of the model is validated to a fire test of empty horizontal furnace executed in the fire laboratory, which was except other carried out to harmonize initial settings of burners in the model. Then, the virtual furnace is used to investigate thermal behaviour for fire-resistance test of a steel beam. The results of the virtual furnace illustrate the great potential for investigating the thermal behaviour of fire-resistance tests.
