以某大型购物中心中庭为例,利用FDS模拟火灾时烟气的运动,分别对中庭周围楼层的防火卷帘全部正常工作、部分防火卷帘失效等5个火灾场景进行模拟计算,得出烟气温度、能见度的变化规律,进而分析该大型购物中心的火灾危险性,并进行人员疏散安全性评价.%Taking atrium of a large shopping center as example, using FDS simulating smoke movement, five scenarios were simulated including all fire shutters around the floor failure and some fire shutters failure, the rules of temperature and visibility change were obtained, and fire risks and people safety evacuation were analyzed.
