Collaborative Evacuation Strategy of Ultra-tall Towers among Stairs and Elevators

With the higher ultra-tall towers development, there are more difficult designs in evacuation. The collaborative evacuation among stairs and elevators was put forward based on analysis of the advantages and disadvantages of elevators for evacuation of ultra-tall tower. Then the principle of collaborative evacuation strategy and design key points were advised. At last, with an ultra-tall tower as an example, the evacuation strategy was introduced, and it was proved feasibly and superiorly according to compare with the different evacuation scenarios formulated by Pathfinder.
