Abstract

Abstract: In view of low efficiency of active evacuation from multi-story apartments, a concept of passive evacuation mobilization for people notification was introduced and a method was worked out for selecting the best notification plan of evacuation. The method was applied to the passive evacuation from the west-9 dormitory in a certain university taken as an example. A simulation comparison in evacuation time was made by using Pyrosim and FDS+Evac between the method and those used in common evacuation schems.The results show that the evacuation time, when the passive evacuation mobilization plane is used, is obviously shorter than those when the common evacuation schems are used, and the plan 3pp4-1 results in the shortest evacuation time, namely 696.8 s, that improvement of familiarity with main exit has a significant effect on the plan with the longest evacuation time, and that there is a logarithmic function relationship between the time delay of opening of the fire door and evacuation time of 95% people .

Key words: multistory apartment, passive evacuation, evacuation mobilization, scheme optimization, evacuation efficiency
