摘      要：It is well known that the use of woods as construction materials can embody carbon content of structural members,which can enhance the urban ***,due to the combustibility of wood,its current application is *** broaden the application of wood,its thermal responses exposed to fire(high temperature)is investigated in this ***,the wood kinetic parameters are determined by coats-redfern method using thermal gravimetric(TGA)***,the density and thermal conductivity are obtained from parallel and series ***,the specific heat capacity formula is presented considering latent and decomposition heat,which can be directly determined by differential scanning calorimetry(DSC).Finally,the one-dimensional nonlinear heat transfer model with apparent thermo-physical properties is *** four-sided heating experiment of Laminated Veneer Lumber(LVL)is carried out to investigate the temperature *** results show that the proposed model can predict the thermal responses of timber structures subjected to fire and high temperatures precisely.
