Design of Catwalk of Tongtian Bridge

  • Publish Date: 25 Apr 2003
  • Tongtian bridge is a foot bridge in Jiulonghsan tourism region, Zhejiang province. Its main span is 208 m. It is light in weight and has good anti-wind properties. A special cable truss structure is adopted. The bridge span consists of the supporting cables, the backward pulling cables, the cables for road surface, the anti-wind cables, and so on. To increase the structural stiffness and stability, all the cables are prestressed. The construction is difficult, because of the spatial structure of the bridge tower, the main cables and those for road surface. The design scheme and nonlinear calculation applied in the design are presented in this paper. The curves and stresses of the cables are calculated under the static and dynamic loads.
