Abstract
This study examines the impact of sky-bridges, as an egress component, on total evacuation of a high-rise building by using an evacuation model named Pathfinder. Five scenarios, with different combination of aspects such as height of the building, number of sky-bridges (and the subsequent inter-distance between them), and people allocation have been simulated. The comparison between the results from the simulations indicates that sky-bridges significantly shorten the total evacuation time if used by all occupants above or at each refuge floor. Furthermore the comparison between the scenarios with different heights and the same inter-distance between the sky-bridges shows that the total evacuation time is approximately the same, as the...

This study examines the impact of sky-bridges, as an egress component, on total evacuation of a high-rise building by using an evacuation model named Pathfinder. Five scenarios, with different combination of aspects such as height of the building, number of sky-bridges (and the subsequent inter-distance between them), and people allocation have been simulated. The comparison between the results from the simulations indicates that sky-bridges significantly shorten the total evacuation time if used by all occupants above or at each refuge floor. Furthermore the comparison between the scenarios with different heights and the same inter-distance between the sky-bridges shows that the total evacuation time is approximately the same, as the buildings are divided in zones containing equal number of floors. However the comparison between two buildings with the same height but different inter-distance between the sky-bridges point out that the total evacuation time increases with increased inter-distance between the sky-bridges and vice versa.
