| 摘 要： | 为了正确分析钢筋混凝土构件截面温度场,以矩形柱为对象,以标准火作用为受火条件,采用数值计算方法,研究混凝土骨料种类和边界条件对截面温度场的影响。研究结果表明:因热参数差别较大,硅骨料构件截面温度明显高于碳骨料,而法国规范推荐混凝土的温度接近硅骨料混凝土的温度,温度值越高其间差别越小;是否考虑边界单元格热储存对温度场影响不大。

| Abstract: | In order to analyze the section temperature field of reinforced concrete members correctly,using numerical method,study was carried out on the impact of concrete aggregates type and boundary conditions on the temperature field,which used rectangular column as the object and standard fire as the fire condition.The results show that because of different thermal parameters,the section temperature of silicon aggregate member is higher than the member of carbon aggregate obviously,and the temperature of concrete... |
