| 摘 要： | 哑铃形钢管混凝土拱肋作为钢管混凝土拱桥的主要受力构件，其建模方法是否合理对全桥结构的安全性具有重要的意义。文章采用MIDAS软件，对哑铃形钢管混凝土拱肋进行了多种简化模拟，并将这些简化模型计算结果与运用AN—SYS软件建立的板、实体单元模型的计算结果进行了比较，以研究探讨较为合理适用的简化建模方法。

| Abstract: | As the main stress component of steel pipe concrete arch bridge,whether the model construction method of dumbbell shape steel pipe concrete arch rib is reasonable is very significant to the structural safety of the whole bridge.By using MIDAS software,the article made various simplified simulation of the dumbbell shape steel pipe concrete arch rib, and compared the calculations based on these simplified model with those based on the plates and solid element models constructed by using ANSYS software,so as to study and discuss simplified model construction methods which are more reasonable and more applicable. |
