| 中文摘要: |
| 对目前常用的性能化防火分析中的安全疏散时间判据进行了讨论,认为存在必要而非充分条件的缺点,给判断是否真正安全带来不确定性,因此提出了一种更为合理的安全疏散时间判据,具有满足充分必要条件,简单可靠,使用方便的优点。该文还通过一个有关大空间建筑性能化防火分析的典型案例进一步阐明了该时间判据的使用方法,得到了合理有效的分析结果。 |
| 英文摘要: |
| The common criterion of safety egress time for performance based fire protection analysis was discussed in this paper. Its shortcoming such as Necessary but Non sufficient condition was found, which brings uncertainty to judging whether the provided fire safety is adequate. Therefore, a simple, reasonable and reliable criterion based on the timeline was presented, and a typical case for larger space building was used to demonstrate the application. |
