| 摘 要： | 调研国内外规范及实际工程钢结构防火保护情况。以某机场航站楼大空间建筑为例,通过CFD计算火灾时屋顶钢结构温度,建议对8m高度以下的钢结构柱进行防火保护,耐火极限不应小于2.50h,8m以上高度可不进行防火保护。并用数值模拟分析钢结构力学性能,用经验公式计算火羽流温度,对该建议进行验证。

| Abstract: | Standards and the steel structure protection in practical projects were investigated.Taking an air terminal,which is a large space building,as an example,the steel structure temperature on the ceiling during the fire development was calculated by CFD,and suggestion was given that there should be fire protection of more than 2.5 h for steel column below 8 m,and the fire protection can be skipped above 8 m.In order to verify the conclusion,mathematical simulation was conducted to analyze the mechanical properties of steel structure,and empirical formulas were used to calculate the fire plume flow temperature. |
