摘要
疏散设计是超高层建筑防火设计重点,为缩短超高层建筑火灾人员疏散时间,利用Pathfinder疏散软件研究疏散楼梯数量和辅助疏散电梯对超高层建筑人员疏散时间的影响,结果表明:增加疏散楼梯数量可极大地缩短超高层建筑人员疏散时间,在满足设计疏散宽度条件下,额外增加一部疏散楼梯,人员疏散时间可缩短50%;利用电梯进行辅助疏散可缩短整体疏散时间,最多可缩短约7 min,且对疏散能力较弱的特殊人群是一种行之有效的疏散方式。
Evacuation design is the key issue of fire safety design for super high-rise buildings.In order to shorten the evacuation time of super high-rise buildings in case of fire,pathfinder evacuation software was used to study the impact of the number of evacuation staircases and auxiliary evacuation elevators on the evacuation time of super high-rise buildings.The results show that increasing the number of evacuation staircases can greatly shorten the evacuation time of super high-rise buildings;with the staircase design meeting minimum width requirements for evacuation,adding an additional evacuation staircase can shorten the evacuation time by 50%;the use of elevators for auxiliary evacuation can shorten the overall evacuation time of the building by up to 7 minutes,which is an effec⁃tive way for the evacuation of people with weak evacuation ability.
