Abstract

The paper substantiates the possibility of using the elevators as the main evacuation path from high-rise multi-storey buildings. The analysis of the reasons preventing effective evacuation of people from high-rise buildings is carried out. A tall multi-storey office building was modeled in the Pathfinder software package. Several scenarios of the human flow are presented, and the influence of time parameters (the beginning of evacuation and delay of signal delivery), the composition of the flow (different ratios of people of different mobility groups), and the level at which the evacuation of each group begins are reflected on the time of evacuation using elevators. The time of evacuation by a staircase is compared with the time of evacuation using elevators. It is shown that it is effective to use evacuation elevators in 60-storey buildings, but it is not rational to use them for a 20-storey building.

Highlights

Every year the number of high-rise buildings and structures increases
Evacuation ways are too long so even healthy people will suffer from fatigue when they are moving to such long distances, For orderly people and people with reduced mobility (PRM) this evacuation method becomes especially difficult, dangerous, and at times physically impossible [1]

Summary

Introduction

Every year the number of high-rise buildings and structures increases. In such buildings, evacuation ways are too long so even healthy people will suffer from fatigue when they are moving to such long distances, For orderly people and people with reduced mobility (PRM) this evacuation method becomes especially difficult, dangerous, and at times physically impossible [1]. It is worth mentioning separately that evacuation from the Twin Towers after the terrorist act with the help of elevators saved up to 3000 lives [5]
