Calculating the Fire Resistance of Exposed Wood Members:Technical
Report 10
Introduction
The superior fire performance of heavy timbers can be attributed to the
charring effect of wood. As wood members are exposed to fire, an insulating
char layer is formed that protects the core of the section. Thus, beams
and columns can be designed so that a sufficient cross section of wood
remains to sustain the design loads for the required duration of fire exposure.
A standard fire exposure is used for design purposes.
