Phased evacuation algorithm for high–rise buildings

Abstract

The article explores a new phased evacuation algorithm for high-rise buildings and structures. The necessity of using this evacuation type is justified by reducing of the human flow density, which minimizes the people injury risks and the crowd formation during the movement process. This type of evacuation prevents the appearance of clusters in local narrowing places (the floor entrance), as well as on stairway. The calculation model is made in Pathfinder PC. The scheme of organizing a phased evacuation is based on the separation of the evacuating people flows and the prevention of their crossing. The design scheme is given for the twenty-story section of a high-rise building. A detailed instruction describes the process of dividing a section into stages and determining the sequence of evacuation floors. The time delays table is calculated for each floor of the simulated twenty-storey section.
