| 摘 要： | 本文采用有限元软件MIDAS/Civil建立模型,分析拱肋和拱肋间横撑对其连续梁拱桥的稳定性的影响。从分析结果可以看出,拱肋横撑对结构稳定的影响较大,减少拱肋间的横撑和横撑间的上下、前后斜撑,结构稳定系数明显减小,且横撑的位置不同,对结构的稳定性也有影响,但影响不是很明显;通过计算改变拱肋钢管的直径、钢管壁厚得出增大钢管的直径和钢管壁厚都可以增大结构的稳定系数。

| Abstract: | In this paper,finite element software MIDAS/Civil was used to analyze the stability of the arch of a continuous beam.The results showed the Rib Crossbars greatly impact the structural stability.Reducing the cross brace between the ribs and between the upper and lower cross brace significantly reduced the structural stability.The position of cross struts also had an impact on the stability of the structure. |
