Abstract

Fire protecting solutions relating to large scale wooden roof structures in industrial buildings. According to the German guideline for industrial buildings, like storage and production facilities and German standards, such as DIN 18234-2 the use of timber and wood based products is limited. And erecting of wide span representative timber structures often needs special permission by authorities. Therefore structural elements have to be designed for a certain fire resistance, depending of building size and further active protection methods. This is also achievable with structural timber elements. However the use of prefabricated timber frame roof elements is currently not allowed, unless passing a specific fire test, if compartment size is excessing 2 500 m2. These elements have to show a limited contribution to flame spread at surface and inside the elements, no further smouldering after fire exposure and a specific fire resistance under natural fire conditions in accordance with the German test standard DIN 18234-1. Within the scope of a research project the behaviour and performance of timber frame elements for large scale roof systems were examined in the case of fire. In this process the effect of flame spread at exposed lining and inside the elements, the protection capacity of lining under parametric fire exposure as well as measures to avoid glowing combustion inside the elements were analysed, to reach sufficient level of fire safety for the plane elements, junctions, penetration areas and the entire structure.
