Analysis of failure probability of traditional wood structure fire suppression
In order to study the probability of fire failure of wooden structures in traditional villages,the failure func-tional function of traditional villages was proposed by using the fire brigade intervention model and Benichou model.The JC method was used to calculate the check point value,and the probability of fire extinguishing failure was anal-yzed by Monte Carlo important sampling simulation.The proposed functional function was used to analyze the proba-bility of fire extinguishing failure of the wooden structure in Lijiang,Yunnan Province.The results show that the failure probability of the village reaches 53.3%,and the probability of fire extinguishing failure gradually decreases with the increase of the opening rate of doors and windows.The uncertainty of the driving time has the greatest impact on the failure probability,and the uncertainty of the opening rate of doors and windows has the least impact on the failure probability.With the decrease of rescue distance,the probability of fire extinguishing failure decreases,and the proba-bility of fire extinguishing failure can be reduced by reducing the rescue distance and increasing the opening rate of doors and windows.
