摘要
高温下钢材力学性能的确定是进行钢结构抗火反应分析的重要组成部分,为此进行了一系列钢材高温材性试验.基于对试验结果的分析,提出了便于应用的钢材三折线高温材性模型,为较精确地进行结构火灾反应分析奠定了基础.
The determination of mechanical behaviour of structural steel at high temperatures is of particular importance for fire resistant analysis of steel structures. For this reason, a series of tests on the material properties of steel at elevated temperatures are conducted. Based on test results, a trilinear material property model is proposed, it permits the fire response analysis of steel structures to be made more accurately.
