摘要
对某办公建筑侧边部分开敞的高大空间火灾风险进行研究,提出了消防设计标准。采用火灾模拟软件FDS,对高大空间的烟气自然填充特征开展数值模拟,模拟结果表明高大空间侧边局部开敞的布置,有利于改善相应高度范围内的火灾烟气控制和人员疏散环境。
The fire risk characteristics of a large space of an office building with a partially open on the side were studied and the related fire protection design standard was proposed. The natural filling characteristics of fire smoke in the large space was simulated applying the specific software FDS and the results showed that the layout of partially open on the side of the space is beneficial to improve the fire smoke control in the corresponding height range and the evacuation environment.
