BuildingEXODUS在优化建筑安全疏散设计中的应用

Application of buildingEXODUS in optimizing the safety evacuation design in a building

利用模拟软件BuildingEXODUS对存在安全隐患的某剧院五层包厢的疏散设计进行了模拟,针对不同疏散设计方案的关键参数分别进行了模拟计算,包括疏散时间、死亡人数、跳跃座位次数、疏散出口的有效性等。结果表明:增加疏散通道的宽度可以减少疏散时间、降低人员伤亡。增加疏散出口的数量可以有效降低疏散时间和跳跃座位的次数,避免火灾对人群疏散的影响。五层包厢增加两个出口的设计为最优设计。

Simulation calculations by BuindingEXODUS were ac- complished to the fifth floor in an opera, in which some fire po- tentials may exist. To different evacuation designs some impor- tant parameters were simulated respectively, including evacua- tion time, death of occupants, jumps of seats, correct distribu-tion of exits etc. The results showed that the evacuation time and casualties could be reduced by increasing the width of evac- uation routes. The evacuation time and the jump over the seat could be reduced by adding the number of evacuation exits, to avoid the effect by fire on people. Adding 2 exits at fifth floor was the optimum design.
