| 摘要: |
| 为了研究火灾时大空间建筑内受火钢构件的温升规律,进行了真实的全尺寸钢构件受火温升实验,采用集总热容法建立了大空间建筑火场钢构件温升理论模型．提出了大空间建筑非规律性变化的烟气温度场预测方法和受火钢构件温度场预测方法．实验数据对比理论计算结果表明,结合非规律性变化的烟气温度场,大空间受火钢构件升温模型能够很好地预测大空间受火钢构件温升变化,预测结果与实验数据基本相吻合． |

| Abstract: |
| In order to study the temperature rise in the steel components exposed to fire, experiment was carried out in one large space building and a theoretical model was built in which the influence of flame radiation on the temperature rise of steel components was taken into consideration. The calculation methods for the thermal radiation from the flame and temperature development in steel were proposed, and the calculated results agree well with the experimental data. |
