摘要
通过有限元程序ANSYS模拟温度场的方法和某桥实测数据比较,分析了影响预应力混凝土箱梁模型温度场分布的因素,得出了太阳辐射吸收系数对计算结果的影响比较大的结论,该结论对计算预应力混凝土箱梁的温度应力和挠度有一定的意义。
By comparison of the calculation temperature field using finite element program ANSYS and measured data of some bridge,the influencing effect of concrete box beam model temperature field distribution was analyzed,it can be got that absorption coefficients of solar radiation has large effect on the calculation results.This result has a certain meaning to calculate the temperature stress and deflection of prestressed concrete box beam.
