Prędkość zwęglania drewna w analizie pożarowej konstrukcji drewnianych

Intensive heating of elements of timber structures in the fire leads to the damage of these structures. Wood is a combustible material and the thickness of the charred layer influences on the shape and dimensions of the cross-section. The paper deals with charring rate of wood as an important parameter in fire resistance of timber structures. The change of charring rate depend on the various properties and factors (density, moisture content, time, heat flux), therefore more research should be carried out to determine a calculation models for the charring rate of wood.
