四级耐火等级历史沿用建筑改造的消防设计
Discussion on the fire protection design of the reconstruction of class IV historical building
【摘要】 根据历史沿用建筑的建筑特点、结构特点、功能特点、人员特点和消防设施情况,确定了安全目标一是保证人员安全,二是保护财产安全。运用调查类比、理论分析、数值模拟等手段,依据国内外建筑防火规范、火灾科学与消防工程研究成果和业主及设计单位提供的资料数据,针对可燃物特性进行了火灾场景设计,针对工作人员与人群特点进行了人员疏散评估研究,针对火灾烟气蔓延特点进行了火灾烟气模拟研究,最后给出了结论和建议。
【Abstract】 Safety objectives have been confirmed based on the building geometry, structural and functional characteristics, personal properties as well as the fire equipment conditions: first is the safety of people, then the property. By using investigation and analogy, theoretical analysis and numerical simulation, fire scenarios have been designed. Evacuation evaluation has been done according to the characteristics of the staff and smoke development has been simulated based on the properties of smoke. Finally, conclusions and suggestions have been given.
【Key words】 historical building; fire scenario; smoke simulation; fire safety engineering; evacuation; evaluation;
