Means of escape ‐ 1988. How close are we to modelling egress from buildings in fire?

摘要

AbstractDuring the last twenty years a number design methods for calculating the movement of people in buildings have been developed. This presentation briefly reviews some of these modelling efforts. Furthermore, it discusses some aspects of the pedestrian movement and addresses an egress model based on the data provided by Predtechenskii and Milinski. This model is applicable to the evacuation of multi‐storey buildings via staircases and predicts the flow movement in terms of time with regard to the building's layout and the interdependencies between adjacent egress way on this model, written in GWBasic language for any IBM‐compatible personal computer. The program is built up as a dialogue between the user and the computer, where the escape route configurations (the width and the length of each section) as well as the number of the persons are put gradually during the course of the computation. The program enables the user to change the dimensions of the building's means of escape and the occupant load easily and work out the influence of the variation on the complete circulation system. Recently, the program also calculates the flow movement under decreased visibility conditions on smoke filled escape routes based on japanese measurements about the walking speed of pedestrians in fire sm
