摘要
研究火灾烟气对国家大剧院壳体钢结构的影响。运用场模拟和经验公式相结合的方法 ,计算了火灾时公共大厅的温度场分布 ,验算钢结构的温度低于 2 5 0℃时 ,不会被火灾破坏。
The purpose of this paper is to study how the high-temperature smoke would affect the steel constructions of the national theater. CFD method and empirical equations are employed to calculate the temperatures in the huge public hall interactively. A steel construction safe temperature of 250℃ is determined, and the calculated smoke temperatures are under the determined steel construction safe temperature, which proves the steel constructions of the national theater will not be damaged by the smoke produced in fires.
