摘要: 在日照作用下对钢管混凝土构件进行截面温度场测试，分析了截面温度场随日照方位及截面空间分布的变化规律。结果表明，截面温度场随时间及截面空间变化的非线性均很显著；钢管表面各测点与圆心测点出现温度峰值的时间存在相位差；沿截面直径方向，各测点温度变化随直径缩小趋缓，即越靠近圆心，测点温度变化越滞后于环境的变化；圆心点的温度变化受各个方向温度变化的共同作用，但更多地受到强势方向的影响。

Abstract: The experiments of temperature field of vertical CFST member under solar radiation are carried out, and the temperature field which is changed with sunshine orientation and sectional distribution is analyzed. The results indicate that temperature field of CFST member caused by solar radiation is nonlinear, and is changed significant with time and section. The peak temperature of measured points which in the surface of steel tube and in the center of concrete occur in different times. Along the radial direction, temperature vary laggardly when the point of concrete in the same series is more close to the center. The temperature of the center point is affected by various directions, especially the strong potential.
Key words: concrete filled steel tube(CFST); solar radiation; temperature field; nonlinear
