Abstract:

The goal of this study was to implement the latest heat-straightening repair technology on a Louisiana Bridge. The bridge chosen was an overpass just east of Lake Charles crossing 1-10. Working with both state and district personnel, the bridge was repaired during August 1998. A facia noncomposite beam had been impacted and the bottom flange displaced 18 inches (0.45 m). The repair was designed by the LSU team and implemented in conjunction with DOTD personnel. Described in this report are the design of the repair, the step-by-step implementation, and a discussion of lessons learned. It is concluded that heat straightening is an effective alternative for repairing damaged steel bridges.
