【摘要】 为解决城市更新中不同建设工程消防改造设计难点，针对文物建筑与既有建筑组合类工程，提出应根据不同保护要求及性能目标进行区别性消防设计，同时还应考虑建筑整体消防安全，对此类特殊形式的建设工程提出消防设计方法及思路。选取某组合式改造项目为研究对象，提出不同区域消防补偿策略及整体消防提升措施，通过FDS和Pathfinder验证消防补偿措施的有效性；采用消防安全评估计算优化后建筑整体消防安全水平，综合判定其具备投入使用的消防安全技术条件，且不低于原消防安全水平，为类似活化利用改造工程的消防设计提供参照。更多还原

【Abstract】 In order to resolve the fire protection design difficulties of different construction projects in urban renewal development,this paper puts forward that the fire protection design should be carried out according to the different protection requirements and performance objectives, and the fire protection safety of the whole building should also be considered, the fire protection design ideas and methods are put forward for this kind of special construction projects for the activation and utilization project of the combination of cultural relics and existing buildings. At the same time, this paper selected a project as the research object, and put forward different fire-fighting compensation strategies for different areas and overall fire-fighting promotion measures. Firstly, the effectiveness of fire compensation measures were verified by FDS and Pathfinder; The overall fire safety level of the optimized design was calculated by the fire safety assessment, the fire safety level means the project had the technical conditions of fire safety for using, and was not lower than the original fire safety level. It provides reference for similar renovation projects.更多还原
