【英文篇名】 Determination of simultaneous opening door quantity for high-rise buildings in case of fire 【作者中文名】 王砚玲; 高甫生; 【作者英文名】 By Wang Yanling★ and Gao FushengHarbin Institute of Technology; Harbin; China; 【作者单位】 哈尔滨工业大学; 【文献出处】 暖通空调, Hv 火灾; 同时开启门数量; 安全出口; 疏散人员数量; 概率; 【英文关键词】 high-rise building; fire; simultaneous opening door quantity; exit; evacuation occupant quantity; probability; 【摘要】 应用概率理论对高层建筑火灾时防烟楼梯间同时开启门数量的确定进行了分析。结果表明,高层建筑火灾时同时开门楼层数与建筑疏散人数、疏散出口数量、有效疏散时间、建筑物总层数、疏散出口宽度、疏散出口流动系数等因素有关,每个安全出口负担的疏散人员数是影响防烟楼梯间同时开门楼层数的关键因素,当每个安全出口负担的疏散人员数超过75人/层时,为了减少同时开门楼层数,应适当增加安全出口数量。 【英文摘要】 Analyses the simultaneous opening door quantity in smoke-preventing stairwell with probability theory. The result shows that the simultaneous opening door quantity has correlation with evacuation occupant quantity, exit quantity, effective evacuation time, building total story number, exit door width and occupant’s flow velocity at exit. Occupant quantity at each exit is a key issue, when the occupant quantity in one story exceeds 75, the safe exit quantity should be increased to decrease simultaneous openi... 【基金】 哈尔滨工业大学跨学科交叉性研究基金资助项目(HIT.MD2001.33)
