| 中文摘要: |
| 针对某地下大型商业建筑消防设计在防火分隔方面存在的问题,分析几种常用防火分隔方法的适用性,初步设计几种防火分隔替代方案。采用建筑防火性能化设计思想,分析替代方案所应达到的安全目标,利用火灾动力学模拟软件FDS评估这些方案的分隔效果,给出火灾时防火卷帘迎火面和背火面的温度发展曲线。数值模拟结果表明防火分隔方案3能够达到防火墙的分隔效果,满足该建筑的消防安全要求。 |
| 英文摘要: |
| This paper aims at achieving efficient fire-resistant partition schemes to replace the firewall in big underground business buildings.Some schemes traditionally used in fire-resistant partition design are presented in the paper and three suitable candidate schemes are developed preliminarily.The safety objective of the fire-resistant partition design is reached by applying the performance-based fire protection ideas.A numerical study on the application of the three schemes is presented by the CFD tool of Fire Dynamics Simulation(FDS) and the temperature distributions are obtained.The results demonstrate that the third scheme is most feasible for the underground business buildings. |
