Estimation of evacuation time with elevator application in high-rise buildings

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.
