火灾下H型钢梁温度场的模拟

Simulation of temperature distribution of H-steel beam in fire

采用有限元法,对钢梁在火灾标准温升温曲线作用下的温度场进行了分析,并用Visual C++进行编程,将计算结果与试验结果进行比较,得出所设计的温度场程序合理,基本可以对火灾温度下梁截面温度场进行温度计算的结论。

Finite element method is used in the temperature distribution analysis of steel beam under standard fire.And apply Visual C＋ ＋ to plait procedure,compared caculate result with test result,conclude that the designed procedure of temperature distribution is reasonable,can caculate temperature distribution of the beam under fire.
