| 摘 要： | 对钢结构进行抗火设计时,需要对钢构件进行温升计算.对于重型钢构件或构件不均匀受火作用以及构件表面保护层不同时,其截面温度分布很不均匀,温差将对构件截面内的应力场产生很大影响,因而也就影响到构件和这个结构在火灾下的反应.由于构件截面边界形状复杂,且火灾升温函数任意

| Abstract: | Finite element method is used in the temperature distribution analysis of steel beam under standard fire. The transient temperature contours and curves varying with time acquired from numerical simulation and experiment are quite identical. It is showed that this method is correct and feasible. A practical approach is developed for temperature distribution of member under fire. This paper has also discussed the influence of section shape of steel beam on the heating transfer. |
