典型室内商业步行街消防设计难点及对策

Key points and strategies analysis of fire protection design based on typical indoor commercial pedestrian street

总结了室内商业步行街防火设计的规范要点,针对典型工程案例消防设计中遇到的难题,从步行街长度定性,步行街与主力店之间的防火分隔,人员安全疏散等几个方面进行了研究。在兼顾建筑特性及商业运营需求的同时,提出了合理可行的消防安全策略,并采用FDS和Pathfinder数值模拟软件进行消防策略的有效性验证,以期为其他室内商业步行街的防火设计提供参考。

Key points of fire protection design on indoor commercial pedestrian street in the code were summaried . Based on the diffi- cult problems which had came across during the fire protection de- sign of a commercial pedestrian street, the longth of the street, the fire separation between the street and main stores, the design of evacuation were analyzed. By taking both building characteristics and business requirements into consideration, feasible fire safety strategies were proposed. Then, the effectiveness of these strate- gies were authenticated by doing FDS and Pathfinder numerical simulation, hopping to provide references for the fire protection de sign of the similar projects.
