The influence of lateral brace stiffness and arch lib section type on the natural vibration property of the bridge is also studied.
以湘潭湘江四大桥为工程背景，分析了横撑对斜拉拱桥稳定、自由振动和抗震等力学性能的影响。
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。
A brace in the engine compartment guarantees additional rigidity to cope with higher lateral forces.
在机舱梅开二度，保证高附加刚度来应付侧向。
Buckling-Restrained Brace (BRB) offer lateral restriction to the steel core to avoid it to buckle, when being suffered big press or pull, and the steel core always can yield.
防屈曲支撑是通过在支撑钢芯外围附设防止其整体失稳的约束单元，在限制支撑发生屈曲的同时能够使其在较大拉压荷载作用下都表现出全截面屈服。
