Abstract

Measurements of the emissivity of hot dip galvanized steel have been performed as a function of temperature from about 200 to 650[deg]C. These results have been used to calculate the temperature increase of a fire-exposed galvanized steel surface according to the European Recommendations for Fire Safety of Steel Structures. It can be concluded that the radiative heat transfer dominates over the convective heat transfer after some minutes. Using a constant estimated value for the emissivity can lead to discrepancies with a real situation. Under certain circumstances a step function for [var epsilon](T) seems useful.
