摘要
采用有限元方法分析由于防火涂料局部破损而造成的火灾下钢构件内的三维热传导问题,给出构件内温度的分布规律。之前先用该有限元模型分析防火涂料完整的钢构件内的二维热传导问题,并将有限元结果与利用傅立叶导热定律建立的传热方程的差分结果进行对比,从而验证了有限元方法进行温度分析的可行性及可靠性。
The Finite Element Approach is used to analyze the temperature distribution of steel members covered by fire insulation subjected to fire. Compared with the theoretical result, the possibility and reliability to use FEA is verified. Then the effect of local damage of fire insulation on temperature distribution of steel members subjected to fire is presented in the paper by FEA since accidental damage happens frequently during interior decorations.
