【摘要】:以某会展中心为建筑模型,结合此类建筑大空间、大跨度的特点,对建筑物的排烟系统设计进行分析,评估该排烟系统设计的有效性。通过设定火灾场景、参阅相关设计规范及标准、利用FDS软件及Pathfinder软件模拟计算,分析在火灾不同场景下、以及火灾不同阶段时的烟气流动情况,模拟在安全时间内人员有效疏散的情况,最终确定采用机械排烟和自然排烟有机结合的方式进行排烟,同时提出针对性的相关措施,为类似的会展类建筑排烟系统设计提供了参考。
[Abstract]:In an exhibition center for building model, combined with the large space of such buildings, characteristics of large span, design and analysis of exhaust system of buildings, to assess the effectiveness of the extraction system is designed. By setting the fire scene, refer to the relevant design specifications and standards, calculated by FDS software and Pathfinder software simulation analysis under different scenarios in the fire well, the flue gas flow in different stages of fire simulation in time, security personnel and effective evacuation, and ultimately determine the use of mechanical ventilation and natural ventilation combined way of smoke, and put forward some related measures, which provides a reference for the design of exhibition building smoke control system similar.
