The influence of hot dip galvanization to the temperature development of unprotected steel members in fire
Abstract eng: If fire safety levels for steel constructions are required passive fire protections have to be added. To optimize these cost intensive applications one verification method is to calculate the critical failure temperature according to EN 1993-1-2. Relating to this, the aim of a national funded research project in Germany is to show the positive effect of a hot dip galvanization on the temperature development of unprotected steel members in fire to replace a passive fire protection for R30 cases related to the nominal temperature-time curve. 1 Economic Relevance The costs of passive fire precautions, for example reactive fire protection systems, are a huge economic deficit of steel concrete composite structures compared to simple concrete construction variants. Therefore, an optimization of the fire safety verification of composite structures is still necessary. Hot dip galvanization already constitutes an economic and efficient way to permanently protect steel components from corrosion. It is hence used successfully for many decades, especially in the area of steel building and recently steel bridge construction. According to Schaumann (2004), about 42% of the Germany´s office buildings have R30 requirements. The total market segment in Germany thus results in approximately 2.5 million m² per year. If hot dip galvanization additionally could contribute beneficially to the fire resistance of unprotected steel members, it would be a huge economic advantage.
