  • Abstract:
    This project allowed the continuation of collecting monitoring data from Bridge #6139061300401 in the John James Audubon Project

    for an additional two-year period. Bridge #6139061300401 was instrumented as part of an earlier project (LTRC Project No. 08-1ST),

    whose fi ndings raised questions about its performance under thermal gradients, which warranted resuming data collection to monitor

    the performance of Bridge #6139061300401 over a longer period of time. The focus of the monitoring eff ort for both projects is on

    the employed continuity detail, which transfers forces between adjacent girders via positive moment reinforcement based on the

    recommendation of the National Cooperative Highway Research Program (NCHRP) Project 12-53. Continuity details are typically used

    to eliminate the need for high-maintenance joints that often lead to the acceleration of element deterioration in the vicinity of the

    joints.
