Influence of Side Stringer to Deck Deformation of Four-Lines High-Speed Railway Cable-Stayed Bridge with Double Cable Planes

Abstract:

Taking Beijiang Bridge as an example, using 3D finite element method, influence of side stringer to deck deformation of four-lines high-speed railway cable-stayed bridge with double cable planes is studied. The results show that the stiffness of the side stringer hardly influence the long wave of bridge deformation and the ratio of deflection to span, but significantly affects the short wave and transversal wave of the bridge deformation. The location of the side stringer influences the long wave slightly, but influences the short wave and transversal wave significantly. If the distance between the side stringer and the center of the main trusses changed, the long wave changes slightly, while the maximum short wave and transversal wave change a lot. The larger the distance, the less the transversal span of the deck and panel beams are, and the less the short wave and transversal wave are. The influence of the axial stiffness of horizontal K-shaped brace to the bridge deformation is small.
