| 摘 要： | 利用有限元分析软件ANSYS,建立了某商场火灾下钢结构温度场模型,模拟了其在实际火场下和ISO834标准升温曲线作用下的温度场分布,将真实火场下商场钢结构的温度场分布与ISO834标准升温曲线作用下的商场钢结构温度场分布进行了对比分析,分析结果表明:ISO834标准升温曲线作用下的商场钢结构温度场分布与真实火场下商场钢结构的温度场分布差别较大,不能完全反应真实火场下诸如商场之类的大空间结构建筑的钢结构抗火反应.

| Abstract: | A temperature field model of steel structure exposed to fire is set up with ANSYS,and the temperature distribution subjected to ISO 834 standard warming up curve and real fire scene are simulated.And the simulated results showed that the mall steel structure temperature field subjected to ISO 834 standard warming up curve and real fire scene are of great difference,and it can't truly reflect the steel structure fire resistance of the large scale building such as mall. |
