NUMERICAL STUDY ON CHARRING PROPERTIES OF ENGINEERED BAMBOO

Fire is one of the most frequent disasters in the world. As bamboo is combustible material, its fire performance greatly limited its structural application. However, study shows that fire safety of bamboo structures can be ensured through reasonable fire design. In this paper, the charring properties of two types of engineered bamboo: laminated bamboo and bamboo scrimber were carefully investigated through numerical study with commercial software ABAQUS. Charring rate was calculated from the simulated 300oC isotherm. The influence of cross-section dimension, fire duration on the charring rate was studied. Two types of engineered bamboo showed similar development rule of charring rate. The charring rate of engineered bamboo decreased slightly with the increase of fire duration.
