Abstract

The article considers elevator application as an integral part of the main evacuation path from high-rise multi-storey buildings and structures. The evacuation ways are rather long in this building type. It makes the evacuation process difficult and dangerous, and sometimes physically impossible. The combined evacuation with using of vertical transport can solve this problem. The complex of buildings of various storeys (20, 30 ... 60) was modeled in the program complex Pathfinder. We determine and compare the values of the evacuation time for different health categories people during movement on stairs and with particular elevator use. The percentage of acceleration of evacuation is given. It is shown that evacuation along the staircase develops as a linear function. The necessary of the joint stair-lift evacuation method increases with the height of the building. We offer the human flow ratios for evacuating people in simulated buildings (20, 30 ... 60), which is made taking into account the various mobility categories.

Highlights

Regulatory documents categorically forbid the use the elevators for evacuation during the fire for a long time in the Russian Federation
Despite the fact that special fire safety requirements are imposed on high-rise buildings [3,4,5,6,7,8], people evacuation in emergency case is not sufficiently reliable in this way
Since there are two ladders in our building, the minimum evacuation time is reduced by 2 times

Summary

Introduction

Despite the fact that special fire safety requirements are imposed on high-rise buildings [3,4,5,6,7,8], people evacuation in emergency case is not sufficiently reliable in this way. It is worth noting that the stairs are not able to provide sufficient capacity to organize the people evacuation from the high-rise building [9]. Evacuation paths usually exceed 100 meters, so it causes fatigue, absent-mindedness and carelessness, which can lead to injuries. This evacuation way becomes especially difficult, dangerous, and at times physically impossible for elderly people and people with reduced mobility [10]
