Abstract(s)

This work presents a numerical approach in arder to predict the behaviour and the perfonnance of typical cellular wooden slabs with rectangular and circular perforations when submitted to fire conditions. For this purpose a 3D numerical model was validated with different experimental tests at real scale obtained in laboratory m four cellular wooden slabs. This study was conducted in accordance with European standard EN 1365-2 and using a fire resistance íümace which complies the requirements ofEN 1363-1. The thermal perfomiance of the slab and the charring rate of the exposed siiïface will be compared for each type of perforations.
