Once a fire resistance rating is necessary, it has to be proven that the load bearing behaviour of a steel construction in the accidental situation of fire still fits the static demands. For this purpose, positive effects of hot-dip galvanized steel members on the temperature development in case of fire has been investigated in this dissertation. The results show a significant better heating behaviour of hot-dip galvanized steel components, due to a lower emissivity. This temperature-dependent physical quantity was determined and quantified in the thesis. Consequently, a significant proportion of fire protection measures for R30 requirements can be omitted by considering this evaluated emissivity of hot-dip galvanized surfaces.
