Abstract:

Recently many new cable-supported bridges have been built especially in Asian countries. Some of them have the potential issues concerned especially on cables. From experiences on the recent projects which author has been involved in, the followings should be taken into account from the viewpoint to develop the better quality of cables for the further projects.

  1. Deeper examination process on the production of high strength wire for bridge cable should be necessary in order to get rid of insecure elements.

  2. More actual experiences on the existing bridges should be reflected in detail design and production for cable anchor.

  3. With regards to installation on suspension bridge cable, more careful planning and execution on cable compaction should be necessary to avoid less quality of cable or damage of wires as much as possible.

These particular issues would sometimes become vital problems in the future of bridge but be sometimes unnoticed at the construction stage.
