Yi Sun-sin Bridge: Influence of the Lateral Rigidity of the Main Cable on the Cable Bands and Wrapping Wire

摘要

The lateral rigidity of main cable formed by a bundle of zinc-coated wires in suspension bridge is relatively small due to the void in the cross-section. Accordingly, the outer pressure on cable loaded by the cable bands and the wrapping wire induce deformation easily. The lateral rigidity of the main cable in the Yi Sun-sin Bridge is measured here and the influence of the lateral rigidity on the cable band and wrapping wire is investigated arithmetically.
