| Abstract: | The design process of steel guide beam for incremental launching construction of Taohuayu yellow river bridge is presented.After comparison and selection,non-uniform solid-web steel plate I-beams are adopted which are connected with steel tubular truss.The cross of steel guide beam is optimized by building finite element model.In order to push forward,the front-end of steel guide beam which connects with bolting and welding joint each other is trunk shape. |
