摘　　要：对某国际博览中心展馆建筑进行性能化设计与评估中,人群疏散时间的模拟计算最为重要。在分析人群类型、人群密度、反应时间区间、不同行为模式等条件下,利用模拟软件Building EXODUS对4个场景的疏散时间进行模拟计算,并对疏散时间的计算结果进行讨论,对产生误差的原因进行了分析。研究结果表明:影响疏散时间的主要因素包括人群的步行速度、反应时间、极端行为等;疏散时间随弱势群体人群比例的增加而延长。Simulation and calculation of crowd evacuation time is ut-most important in Performance-based design and assessment of an International Exhibition Center.In the paper evacuation time of four different scenarios was calculated using building EXODUS-software on the basis of the correct analysis of crowd types,crowd density,response time region,crowd behavior.Then error analysis was carried out according to the discussion of simulation results.The research results show that the factors affecting evacuation time include crowd speed,response time and extreme behaviors.On the other hand,evacuation time will be prolonged with the ratio of disabilities increasing.
