Simulation of Charring Depth of Wooden-based Products when Exposed to Non-standardized Fire Curves

Abstract

Fire resistance of wooden structures is based on the calculation of the charring depth. Analytical models for charring are given in regulations, e.g. the European Eurocodes, only for standard fire curves and for parametrical fires. This paper presents a numerical model for heat diffusion in wooden products and the induced charring. After calibration of the model it is used to analyze the fire resistance of a wooden beam under different fire models, including a non-standard fire curve.
