Eurocode 1992-1-2 includes the following alternative design methods: detailing according to tabulated data, simplified calculating method for specific types of members and advanced calculating method for simulating the behavior of structural members, parts of a structure or an entire structure. For determining the fire resistance of a reinforced concrete slab structure the tabulated data and the simplified calculating method of isotherm 500 are used. Temperature distribution in the concrete cross-section is determined using FEM analysis (ANSYS) and numerical solution (Nonstac) of differential equation of heat transfer. Calculated temperatures are compared with temperature profiles given in annex A of CSN EN 1992-1-2.
