The structure is resolved into several compound elements and every compound element consist of three parts: arch, trussed beam and lateral brace.
整个结构划分为若干组合单元，每个组合单元包括拱、桁梁及竖杆横撑架三部分。

The results show that the set of lateral braces has direct influence on stability of arch-style combination system, while the influence of lateral brace rigidity is slight.
结果表明，横撑的布置方式直接影响拱式组合体系的稳定性，而横撑刚度对全桥稳定性的影响不大。

The influence of lateral brace stiffness and arch lib section type on the natural vibration property of the bridge is also studied.
