摘要
为了研究大空间建筑火场钢构件升温,进行了全尺寸大空间建筑火场钢构件升温实验,并建立了大空间钢构件升温的理论模型.模型中将火源视为点火源,并考虑火焰热辐射对钢构件升温的影响.理论预测值对比实验结果表明,理论预测值与实验结果的绝对误差最大值为1.2℃,绝对误差均值为0.58℃.相对误差最大值为11.65%,相对误差均值为6.47%.
In order to study the temperature rise of steel components in the large space building,the experiment was conducted in one large space building and the theoretical model was built.In the theoretical model,the fire was taken as point fire source and the influence of flame radiation on the temperature rise of steel components was also taken into consideration.Comparison between the theoretically predicted value and experimental results data shows that： maximum value of absolute error between the theoretically predicted value and experimental results is 1.2 ℃,and mean value of absolute error is 0.58 ℃;maximum value of relative error is 11.65%,and mean value of relative error is 6.47%.
