摘要
分析某大型展览中心的消防设计超规范问题,针对这些问题进行性能化设计,计算人员所需疏散时间,并利用FDS和buildingEXODUS计算人员可用疏散时间。结果表明,在保守地设置火灾规模和疏散人数并考虑最不利条件的情况下,各场景验收标准规定的参数均未达到危险临界值,且有较大的安全余量。并在评估的基础上提出提高安全性的建议。
The fire design problems of a large exhibition centre were analyzed, and the performance-based design was conduc ted. The required safety egress time was calculated, and the a- vailable safety egress time was calculated by FDS and build ingEXODUS. Results showed that, when the fire scale and evacuation number were set sparingly, and the most adverse condition was considered, the factors in each scene are all under the dangerous threshold, and have enough safety margin. Safety suggestions were put forward based on the evaluation, too.
