Application of Numerical Simulation Technology in the Analysis of Constructing High-rise Fires

Zhou Biao,Zhang Teng,Xu Youping(Wuhan University of Science and Technology,Wuhan,430081,China)  
It is hard to extinguish the fire in the constructing high-rise buildings and the key to evacuation of constructing high-rise fire is to correctly predict the changes of parameters under catastrophic conditions,in particular,the forecast of scope of the spread of smoke,gas concentration and flame,as well as the proliferation of toxic gases.In order to obtain the fire parameters of the constructing high-rise,the paper uses the FDS(Fire Dynamics Simulator) software developed by United States Institute of Standards and Technology(NIST),builds the model of constructing high-rise buildings,and carries out a full-size constructing high-rise fire simulation,the rule of vertical variation of fire smoke concentration and oxygen concentration temperature.According to the influence of wind speed on fires,a method of preventing the spread of flame is suggested,and the FDS effect is tested,giving a powerful basis for preventing or mitigating fire disasters and decision-making of fire protection.
