Project aims

The aim of this research project is to lay the scientific foundation for fire safety in hybrid steel-timber constructions and thus to provide design methods and construction principles that will finally enable a broad application of the construction method. For this purpose, the specific material and joint interactions are considered with regard to their thermal behavoiur under fire load. In addition to the standard consideration of fire resistance up to 90 minutes under Standard-Fire Curve, the associated foundations are also laid for a performance-oriented natural fire design.

The focus of this research project is focused in the areas named below:

• Quantification of the protective effect of mass timber components (ceiling and wall elements) and timber coverings for steel profiles in case of fire .
• Development of constructive solutions without premature falling-off of coverings
• Exclusion of uncontrollable fires in the component joints between steel and timber
• Enable simple restoration
• Provision of basic principles and material parameters that allow a performance-related design under natural fire load for hybrid steel-timber structures
