A model for the pyrolysis of two Nordic structural timbers

Performance-based design of the timber structures' fire resistance is often based on reduced cross section and thus relying empirical numerical assessment charring propagation. The current work aims to construct models for pyrolysis spruce pinewoods allow coupled simulations cross-section reduction burning rate in models. Kinetic are formulated thermogravimetric data supported by heats combustion measurements differential scanning calorimetry microscale calorimetry, respectively. results from these small-scale consistent with each other, determined wood primary components fitting experimental results. Heat release constructed tests, cone calorimeter experiments used estimation physical properties heat model validation.
