| 摘 要： | 多塔斜拉桥是近年来出现的新桥型,其主梁的温度效应对该类桥型的受力行为有很大的影响。采用ANSYS有限元分析软件对其主梁截面的温度场进行分析时,边界条件的处理是一大难点,文章尝试将太阳辐射转化为等效大气温度的方法,得到了较为满意的结果。

| Abstract: | Cable -stayed bridge with multi -pylons is a new stile these years. The temperature effect of main girder has great influence on its mechanics behavior. It is difficult to do the treatment of boundary conditions when making analysis of temperature field by ANSYS. This paper attempts to transform solar radiation into air temperature, and satisfactory results are obtained. |
