  • What are some possible reasons for not connecting the girder to the pylons and abutments?
    What are the main structural consequences?
  • Wire Rope End Termination

    Figure 5 shows two hanger cables at their bottom ends.

    Hanger cables.
    Hanger cable termination using U-bolt clamps

    The hanger cables are made of steel wire ropes, and the end termination consists of U-bolt clamps. The left hanger cable has two U-bolt clamps, while the right hanger cable has three U-bolt clamps. Wire rope thimbles are not installed.

  • Is the terminal efficiency of the left hanger cable the same as the right hanger cable?
