BuildingEXODUS在人群疏散时间预测中的应用

Application of BuildingEXODUS in predicting crowd evacuation time

利用模拟软件BuildingEXODUS对某办公大楼会议室进行疏散时间的模拟计算,分别得出不同人群类型、不同人群密度、不同反应时间、不同行为模式等条件下的疏散时间,并与疏散时间的传统计算方法进行对比。人群设定分别为儿童与少年、青年、中年、老年、残疾、混合人群。对产生误差的原因进行分析,对建筑设计方案的优化设计、完善建筑防火规范等提供理论和方法上的帮助。

Evacuation time of a meeting room in an office build- ing was simulated by BuildingEXODUS software in various con- ditions, including different crowd types, crowd density, re sponse time, behavioral model. The different crowds were chil- dren and youngster, youth, middle age, old, disabled and mixed people. The reasons of error were analyzed based on comparing to the traditional calculating method. The research results can give some help and guidance in theory and method to optimize a safety evacuation design in a building and to improve the building design code in China.
