摘要
针对民用公共建筑中大跨空间结构屋面防火设防体系中的有关问题,借鉴"处方式"规范中基于构件的防火设防体系和消防安全工程方法的基本理念,利用规范摘录对比和工程实践归纳分析的方法,系统地对建立大跨空间结构屋面防火设防体系需要明确的应用场所及对象分类、设防目标及功能要求、设定火灾及设计耐火时间、荷载效应组合、失效判定准则及方法进行了探讨,提出了效应组合及失效判据的公式化建议,可作为工程防火设计及相关标准制修订的参考。
Against the fire protection design problems of long-span spatial roof structures in public building,the application environment and classification of structural system,fire protection design object and functional requirement,fire and fire resistant duration design,combination of load effect as well as failure criteria and method have been discussed systematically with reference to the fire protection design concept of structural elements in prescriptive codes and fire safety engineering method.Method of comparison of requirements from related codes and summarization and analysis of experiences from engineering practices has been used during the study.The composition of the formula of load effect combination and failure criteria has been given.This paper can provide reference for the building fire protection design and the revision of the related codes and standards.
