  • Prestress Losses and Development of Shortterm Data Acquisition System for Bridge Monitoring
    Prestress Losses and Development of Short-term Data Acquisition System for Bridge Monitoring
    Pace, Justin M ;
    Barr, Paul J.
    2019-06-01 | PDF
    When a vehicle drives over a bridge, each bridge girder carries a portion of the vehicle's weight. This load causes strain in the bottom of the bridge girders. However, depending on where the vehicle is located on the bridge, some bridge girders carry a higher percentage of the vehicle's load. This study investigated the amount of strain typical ve ...
