An experimental study of flame spread over the bamboo slab of different inclination angles and thicknesses
ABSTRACT
Bamboo as a new type of building material, is an alternative raw material for wood and wood-based composites, but its burning could result in fire disaster. The aim of this study was to examine the surface flame spread behavior over the inclined bamboo slab. A series of experiments were conducted using bamboo slabs with thicknesses of 2.5 mm, 3.5 mm, and 5 mm. The flame morphology, flame spread rate, and mass loss rate versus the inclination angle and thickness were measured and physically explained. The results show that the flame spread rate increases with increasing inclination angle of slab and decreases with increasing slab thickness. The mass loss rate is positively affected by the inclination angle, while it is little influenced by the slab thickness. The available flame spread models of thermally thin and thick solid materials underestimate the measured flame spread rates over bamboo slabs. But the thermally thick solid flame spread model is comparatively suitable for the bamboo conditions in this paper. The findings of this study can support the fire permanence design of bamboo structural buildings.
