ABSTRACT
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.
