Abstract
To study the fireproof performance of wooden roof truss, a typical wooden roof truss of timberwork building in a scenic was chosen to conduct thermal_mechanical coupled analysis with finite element numerical analysis software, and the temperature field distribution was calculated and the deformation of roof truss under normal temperature and high temperature was analyzed in this paper. The influence of charring and temperature to deformation and the deformation law of member under normal temperature and high temperature was researched. The results show that high temperature in fire had significant impact on member deformation, the fireproof time of sheathing and rafter was less than 35 min, and the main members of roof truss meet the the requirements supplied by standards.关键词
