摘要
高层建筑火灾情况下的人员疏散性能是评价建筑安全性能、指导人员逃生的重要依据.文中将火灾情况下人员的疏散过程分成觉察、发出警报及行动3个部分,采用经验公式计算得到人员觉察和疏散的时间,并采用水力模型模拟人员在楼梯间的疏散过程,计算高层建筑火灾情况下人员在楼梯和通道的流动时间,实现人员疏散过程的计算机模拟.最后以一栋教学楼为例,计算了危险来临时间和周一到周六各上课时段的人员疏散所需时间,分析了教学楼的安全疏散性能.
The personnel evacuation performance in fire is an important criterion for evaluating the safety of highrise buildings, which can also help to direct personnel escape. In this paper, the evacuation process in high-rise building fire is divided into 3 phases, namely, the detection, the alarming and the action. Then, the empirical equations are used to obtain the time of detection and action, and the hydraulic model is used to simulate the evacuation process of people on the stairway and to further obtain the time needed for passing through the stairway and the passage. Thus, the evacuation of people is successfully simulated. Moreover, a high-rise teaching building is taken as the object to calculate the danger time and the evacuation time in each teaching time range from Monday to Saturday. As a result, the personnel safe evacuation performance of the building is obtained.
