波形钢腹板组合箱梁桥是一种造型美观、受力合理的新型钢—混凝土组合结构,以某波形钢腹板PC组合箱梁跨线桥为背景,介绍了该桥的主梁整体设计、波形钢腹板构造设计、顶底板连接键设计计算,并按施加一期荷载、张拉体外预应力钢束、施加二期恒载、施加活载等施工及营运流程进行波形钢腹板预应力混凝土组合桥梁的上部结构顶底板混凝土应力、波形钢腹板应力及结构刚度(挠度)的有限元静力分析计算,验算其是否符合现行规范要求,为今后类似工程计算提供参考。
The corrugated steel web composite box girder bridge is a new type of steel-concrete composite structure with beautiful appearance and reasonable force. Based on the PC-combined box-beam overpass bridge with a corrugated steel web, the overall design of the main girder of the bridge is introduced , Corrugated steel web structure design, roof and floor connection design and calculation, and according to the application of a load, tensioning prestressed steel beam, the application of two dead load, live load and other construction and operation of the corrugated steel web pre- Stress analysis of the top and bottom concrete stress, the stress of corrugated steel webs and the structural stiffness (deflection) of the superstructure of the bridge with concrete-filled composite bridges are carried out to verify whether they meet the requirements of current codes and provide references for similar projects in the future.
