• Abstract:
  The replacement of the US Grant Bridge over the Ohio River in Portsmouth, OH, was initiated in ; 2001 when the original bridge was closed and demolished, and its substitute opened in 2006. The ; new design is a steel cable stay design with steel girders and floor-beams supporting a posttensioned concrete deck system nearly 65’ wide carrying one lane of traffic in each direction. The ; combination of epoxy-coating, grout filling, and outer tubing provides protection for the all-important ; structural cabling suspension system from both weather and corrosion. Ironically, however, these ; same features make it impossible to gain direct access to either the cables or the interior of the ; anchorages which, in turn, presents special challenges for inspection and rehabilitation of these ; critical bridge components on bridges of this type. It was envisioned that its long-term behavior and ; any associated changes in its structural condition could be best understood with the aid of a ; longitudinal study beginning during bridge construction, one that includes instrumented monitoring of ; both construction/erection and in-service phases of the life of this bridge. Such an approach, ; integrated with traditional bridge management techniques, would help lead to a safe and economical ; realization of the 100-year design life of this structure. A health monitoring system for the bridge ; would be designed, planned, and implemented, with data collection and archival throughout its ; construction and ultimately an automated, user-friendly interface on a dedicated website.
