【摘要】：大空间商业建筑规模大、空间高、结构特殊、火灾危险高，这些建筑在结构形式、使用功能、建筑材料、空间大小等方面都与传统建筑有相当大的不同，对于火灾的预防和救援提出了新的要求，现有的“处方式”防火设计规范已经不能满足当前很多大空间商业建筑的防火要求。因此，性能化防火设计逐渐成为大空间商业建筑消防设计发展的一种趋势，得到越来越广泛的应用。 本文总结了国内外建筑防火性能化设计的研究现状，论述了建筑防火性能化设计方法与设计要点。采用规范与实证分析相结合的研究方法，对大空间商业建筑的特征与火灾特点进行研究，通过国内近十年的大空间商业建筑火灾案例的分析，提出常规消防设计的要点和应用于大空间商业建筑时的问题。引出大空间商业建筑防火性能化设计的要点，从安全目标的确定、性能指标的选择、火灾场景的设定、关键参数的确定与计算几个方面归纳总结，提出性能化设计中应该注意的问题。围绕大空间商业建筑实例——泉州浦西万达广场商业综合体以及晋江海峡西岸国际采购与区域物流中心（简称“美旗城”）两个项目的消防设计开展性能化防火设计研究。针对两个建筑防火方面所存在的消防设计难点，从基于性能化防火设计的思路对建筑方案进行调整，通过分析确定火源位置、火灾增长速率、最大热释放速率，进行了步行街排烟量的计算及烟气运动的场模拟，运用现有的工程学方法对人员安全疏散参数、疏散时间、疏散场景等进行模拟计算，从而建立可靠有效的消防安全防火设计系统，，对该类建筑的消防安全设计及日常运营管理方面提出了有效可行的建议。 本文的研究对大空间商业建筑的防火性能化设计研究具有一定的实践参考价值，有利于进一步促进消防安全设计迈向科学化、合理化和成本效益的最优化，并将产生重大的社会效益和经济效益。
[Abstract]:Large space commercial buildings are large in scale, high in space, special in structure and high in fire risk. These buildings are quite different from traditional buildings in terms of structure form, use function, building materials, space size, etc. New requirements for fire prevention and rescue have been put forward. The existing fire protection design code of "place mode" can not meet the fire protection requirements of many commercial buildings in large space. Therefore, performance-based fire prevention design has gradually become a trend in the development of large space commercial building fire protection design, and has been more and more widely used. This paper summarizes the research status of fire resistance performance design of buildings at home and abroad, and discusses the design method and key points of building fire resistance performance design. This paper studies the characteristics and fire characteristics of large space commercial buildings by combining normative and empirical analysis, and analyzes the fire cases of large space commercial buildings in China in the past ten years. The main points of conventional fire protection design and the problems of its application in large space commercial buildings are put forward. The main points of fire resistance performance design of large space commercial buildings are introduced, and summarized from several aspects, such as the determination of safety target, the selection of performance index, the setting of fire scene, the determination and calculation of key parameters. The problems that should be paid attention to in performance-based design are put forward. This paper studies the fire protection design of the large space commercial building, the commercial complex of Wanda Square in Puxi, Quanzhou, and the international purchasing and regional logistics center on the west side of the Jinjiang Strait (referred to as "the United States Banner City"). In view of the fire prevention design difficulties in two buildings, the building scheme is adjusted based on the idea of performance-based fire prevention design. The location of the fire source, the fire growth rate and the maximum heat release rate are determined by analyzing the fire source location, the fire growth rate and the maximum heat release rate. The calculation of smoke discharge and the field simulation of smoke movement in pedestrian street are carried out, and the safety evacuation parameters, evacuation time, evacuation scene and so on are simulated and calculated by using existing engineering methods. Therefore, a reliable and effective fire protection design system is established, and some effective and feasible suggestions are put forward for the fire safety design and daily operation management of this kind of buildings. The research in this paper has certain practical reference value for the research of fire resistance performance design of large space commercial buildings, and is helpful to further promote the fire safety design to move towards scientific, rational and cost-benefit optimization. And will produce significant social and economic benefits.
