Abstract

Ancient timber buildings have special fire characteristics. In order to put forward feasible fire prevention and control measures, the influence law of the specific structure plank wall on the fire spread was researched. A specific fire in the main hall of Jing'an temple in Shanghai was simulated using Fire Dynamics Simulator(FDS) to obtain the influence of plank wall with different structures on the fire spreading. The results show that the plank wall acts as the main channel for longitudinal propagation of the flame, and the flame longitudinal propagation time increases and flashover delays with the increasing of upper opening size, that the upper opening can accelerate the fire smoke horizontal spreading speed, that different opening sizes have little influence on the settling velocity of smoke layer behind the main hall, and that the condition without opening increases the time that the smoke layer height falling to 4 m by 20 s. © 2019 China Safety Science Journal.
