| Abstrait: |
In the past all large stay cable bridges in Germany were built with locked wire ropes [1]. For a new project, Ziegelgraben-Bridge crossing the “Strelasound”, the contract award also had allowed offers with stay cables using prestressing strands for tendering. Resulting from the good experience with this bridge a second bridge project with stay cables using prestressing strands, a bridge crossing the river Rhine near Wesel, was charged. Since no supplier had a general approval for these strand stay cables many tests according to the newfib-recommendation had been required [2] [3]. Before executing the bridges with stay cables using prestressing strands special requirements for the life time of the bridge were defined to ensure the durability and sustainability of the structure. The exchangeability of a stay cable as well as of a single strand has to be possible. The stay cables of the bridge crossing the Strelasund were installed without mishap. For the Rhine-bridge the tests are finished. Since June 2007 the cables have been installed. |
