摘　　要：针对民用公共建筑中大跨空间结构屋面防火设计问题,总结分析当前普遍采用的防火设计方法的基本出发点和实践效果,及仍存在的科学不足。在此基础上,针对不能满足新的工程实践的状况,指出了完善防火设防体系的需求,并从建筑防火整体视角对大跨空间结构屋面的防火设计给出了部分设计理念、方法的建议,可供工程防火设计借鉴。Against the fire design problems of long-span spatial structure roof,the basic starting point,practical effect and disad vantages of existing general fire protection methods were conclud ed.Considering the disadvantage and the situation of can't satisfy the requirement of engineering practice,the demand of perfecting the fire protection system was suggested.Proposals of design meth ods and concepts related to the fire protection design of long-span spatial roof structures have been put forward from the respect of global fire-protection.This paper can provide reference for the fire protection design of the similar built environment.
