火灾蔓延是导致现代高层建筑物火灾损失的主要因素,按传播方向,火灾蔓延可分为水平蔓延和竖向蔓延。开展火焰、烟气传播路径进行数值研究,对防火设计具有重要意义。本文以某3层建筑为研究对象,建立FDS数值模型,将窗口尺寸和防火挑檐高度作为变量,研究其对窗口喷火的影响,并根据研究结果,提出合理的窗口结构设计方案,为建筑物防火设计提供参考。
The spread of fire is the main factor leading to the fire loss of modern high-rise buildings. According to the propagation direction, the spread of fire can be divided into horizontal spread and vertical spread. Carrying out the numerical study of flame and flue gas propagation path is of great significance to fire protection design. This paper takes a 3-storey building as the research object, establishes the FDS numerical model, takes the window size and fireproof eaves height as variables, studies its influence on the window spouting fire, and according to the research results, proposes a reasonable window structure design scheme, Fire design for reference.
