Abstract
In the past few decades, numerous ultra high-rise buildings have been
erected in the metropolitan areas of many cities around the world. For
the related building designers, building occupants and the governments,
fire safety problem is certainly a major concern, especially after the
collapse of World Trade Center in the 9/11 event. That disaster makes
people reconsider ultra high-rise building evacuation strategies. Of the
current strategies, using elevators in ultra high-rise buildings to
assist evacuation seems to be promising in improving evacuation
efficiency. To quantitatively evaluate elevator assisted evacuation
process, an event-driven agent-based modeling approach is proposed in
the present paper. This modeling approach could capture not only the
movement characteristics of stair using occupants but also the detailed
elevator motion features. The combined effects of occupants' and
elevators' parameters on the evacuation efficiency have been
investigated. Results indicated that the model is helpful to reveal the
dynamics of elevator assisted evacuation, and sometime, using elevators
to move all occupants to ground safety point may not be an optimal
solution. (C) 2017 Elsevier B.V. All rights reserved.
