摘要
针对控制连片木结构建筑火灾蔓延的实验,提供一种数值模拟实验方法。以广西侗族吊脚楼为例,分两次筛选出最危险工况,提出侗族村落中以防火间距和外墙喷雾系统相协同的防火体系,运用FDS对不同建筑布局下的火灾进行模拟,并分析极端情况下吊脚楼防火体系的有效性。
Considering the experiments on controlling fire spread in continuous wood structure buildings, a numerical simulation experiment method was proposed. Taking Dong stilted building as example, the most dangerous working conditions were obtained by screening twice.The fire prevention system of Dong village wasput forward, which was based on fire prevention distance and external wall spray system.FDS was used to simulate fires in different building layouts, and the effectiveness of fire protection system of stilted building in extreme cases was also analyzed.
