以湖南黄花国际机场新航站楼为原型,分析了圆钢管混凝土柱在日照作用下的截面温度场。并采用ABAQUS软件对不同直径的圆钢管混凝土在角柱和边柱受热工况下的截面温度场进行数值模拟。研究结果表明,在相同受热工况下,不同直径圆钢管混凝土柱的截面温度分布规律相近,角柱与边柱沿受热方向的截面温度分布规律相近,大直径柱以及边柱由于受热面积大导致截面平均温度较高。在此基础上,拟合得到角柱和边柱在日照作用下的截面温度场分布模式,计算值与有限元分析值吻合良好。
Taking the new terminal of Hunan Huanghua International Airport as a prototype, the cross-section temperature field of CFST column subjected to sunlight was analyzed. And the ABAQUS software was used to simulate the temperature field of the cross-section of CFST with different diameters under the heating conditions of corner column and side column. The results show that under the same heating conditions, the cross-section temperature distribution law of CFST columns with different diameters is similar, and the distribution of temperature distribution along the heating direction of corner columns and side columns is similar. The large diameter column and side column lead to the large cross-section The average temperature is higher. On this basis, the distribution model of the temperature field in the section of the corner columns and side columns under the action of sunlight is fitted, and the calculated values are in good agreement with the finite element analysis.
