This thesis investigated four kinds of bamboo-wood multiple floors, using"Deformation Expert System of Wood Composite Materials", researched on change of moisture content,longitudinal/transverse dimension and warp deformation.Based on expert system, fundamental parameters were tested. The system simulated size transformation,warp deformation and failure of the four floors under three conditions: the same temperature and RH,constant temperature/RH changed evenly,constant temperature/RH changed unevenly. It showed that the order of longitudinal dimension and warp deformation is: carbonized side pressed floor |
