State of the art in fire protection of multi-storey timber buildings

With introducing the model guideline for fire protective requirements on multi-storey buildings made of timber in the year 2004 it became possible to construct buildings out of timber up to a height of the upper floor of 13 m. For these types of houses the building code requires a non-combustible cladding to prevent the load bearing timber structure from ignition over 60 minutes time. Furthermore, combustible insulation materials are not allowed inside the timber frame construction.
Multi-storey timber buildings built in the last few years often had significant differences to these regulations. Real building projects show that especially service installations and the joints between building elements cause problems in praxis.
The results of the main research projects in this topic are summarized in this paper and references to further reading are given concerning to optimization of the non- combustible cladding, application of combustible insulation and solid timber constructions, integration of service installations and the jointing of different elements.
