The Phenomenon of Extinction of Timber - Experiments and Theory

EasyChair Preprint 7782

Abstract

The phenomenon of self-extinction plays a vital role in predicting the structural integrity of timber structures in mid-and high-rise constructions when exposed to fire. In the present study, the flame propagation, spatial temperature variations with time, and criteria for self-extinction of a Cross Laminated Timber (CLT) block subjected to fire are predicted using the "Unified ignition Devolatilization" (UID) model. The effects of incident heat flux, oxygen concentration on flame propagation, and self-extinction were studied. The mass loss rate (MLR) for different operating conditions were predicted and validated with the experiments done at controlled atmospheres. The model is shown to predict the overall behavior accurately with the predictions of MLR close to the experimental values.

Keyphrases: Timber, devolatilization, flame propagation, model, self-extinction
