某大型体育场馆消防设计性能化评估

The fire risk assessment and evacuation research on a large-scale sport events venues

结合某大型体育场馆设计工程中存在的超出国家现行防火规范的问题,分析体育场馆火灾危险性和防火安全目标。设置5个火灾场景,采用FDS模拟火灾烟气运动,并计算ASET;采用EVACNET4网格节点式疏散模型数值模拟方法计算RSET,从而对其进行火灾风险评估。

Based on the main problems of a large-scale sport venue fire safety design,which overstepped the fire code and standards,the fire hazard and fire safety goal of sport venues were analyzed.Five fire scenes were settled,and FDS was utilized to simulate the smoke movement,and calculated the ASET.EVACNET4 network node evacuating model was used to calculate the RSET.The fire risk was assessed.
