In the design of ribarch bridge, the archrib of variable cross section of weak transverse fixed is adapted usually.
在肋拱桥的设计中，常采用弱横向联系变截面拱肋。

Influence of different camber Angle on special-shaped spatial combination arch-ribarch mechanical behavior is analyzed under completion state.
在成桥状态下，分析了不同外倾角对异形空间组合拱肋拱受力性能的影响。
3
The lateral stiffness of the single ribarch is very small due to it removed the lateral bracing, so the lateral stability of the archrib is the acute issue.
