针对北京某大学图书馆内中庭特点,该文通过设立火灾场景、设计火灾规模、分析烟气控制方法和模拟人员疏散等方法进行模拟验证,最终确定烟控设计策略。结果表明:中庭内部烟控系统设计应综合考虑人员活动高度、排烟量及探测报警等因素的影响;利用全高度自动控制挡烟垂帘可以有效防止烟气侵入各层空间,保护疏散人员的安全。 Aiming at the characteristics of atrium in a university library in Beijing, this paper simulates and verifies the design of fire control system by setting fire scenes, designing the fire scale, analyzing flue gas control methods and simulated evacuation methods. The results show that the design of smoke control system inside the atrium should be based on the factors such as the height of occupants, the amount of exhaust smoke and the detection and alarm. The automatic control of smoke curtain by full height can effectively prevent the smoke from entering the space and protect the safety of evacuees .
