Description

The main goal of this paper is to develop a numerical model to assess the fire behaviour of cellular wood slabs with different drillings. A transient thermal analysis with nonlinear material behaviour will be solved with ANSYS program. The presented numerical model is based on a constructive solution proposed by Frangi and Fontana. The numerical results obtained will be compared with the experimental results from the reference. The developed numerical model allows future studies and simultaneously characterizes the effect of perforations in wooden slabs to minimize the fire risk. The numerical model can easily be adjusted for other constructive solutions, to facilitate the verification of safety in case of fire, in buildings with several wood floors and slabs assemblies.
