钢管混凝土拱桥横梁受力浅析

Analysis on Transverse Beam Force of Concrete-filled Steel Tubular Arch Bridge

对于钢管混凝土拱桥,吊杆和横梁是桥面系与拱肋间传力的纽带,横梁的安全性能直接影响全桥安全,因此有必要对横梁受力进行详细分析。文章以某下承式钢管混凝土拱桥为例,采用桥梁专业软件TDV建立有限元模型对其横梁进行了受力分析,结果表明该桥钢横梁设计合理,横梁构造尺寸满足安全受力要求,对于同类工程具有一定的参考价值。

For the concrete-filled steel tubular arch bridge,the boom and the cross beam are the link of the forces between the bridge deck and the arch rib,the safety performance of cross beam directly affects the safety of whole bridge,therefore, it is necessary to conduct the detailed analysis on cross beam force.with a through concrete-filled steel tubular arch bridge as the example, this article established the finite element model by bridge software TDV to analyze the force of its cross beam,the results showed that the steel cross-beam design of this bridge is reasonable,and the structural dimensions of cross beam can meet the requirements of safety force,thereby it has a certain reference value for similar engineering.
