摘要
基于性能化方法对新建昆明国际机场航站楼屋顶网架结构进行了结构抗火设计。对大型网架结构整体抗火设计问题进行了探讨。推荐了一种钢结构抗火性能化设计的设计流程。介绍了抗火性能化设计中高大空间火灾下钢构件升温的实用计算公式。讨论大型网架结构抗火整体分析中的温度加载模型。推荐了适用于钢结构抗火整体分析中的荷载组合方法。
Performance-based method (PBM) is adopted Kunming airport. Fire resistance design of large fire resistance design of steel structures is given to do fire resistance design of grid struct ce grid st by global analysis ures of studied. the temperature the roof of new A procedure for elevation of steel members in large space fire is introduced. Discussion on the influence of temperature condition in global analysis of fire resistance of large space grid steel structures is given. A load combination method used in global analysis of structural fire safety is proposed.
