大空间钢结构建筑消防安全评估研究

The Assessment of Steel Frame Structure of a Spacious Building

大空间钢结构建筑发生火灾时,火焰及火灾产生的高温羽流可能对钢构件构成一定威胁。采用经验公式计算和FDS模拟分析两种方法计算火灾环境中大空间建筑钢构件的温度,评估钢构件是否达到或超过其失效温度。

The components of a steel frame structure are to be threatened by high temperature in a spacious building when a fire occurs.This paper uses an experience formula and FDS simulation analysis method to compute the temperature of the components in a spacious building to test.
