| Abstract: |
This paper describes the instrumentation and monitoring of the 50 spans of the Champlain Bridge in Montreal using optical sensors at mid-span for recording flexural strains on the exterior post tensioned girders. These girders were subjected to structural degradation due to corrosion of the strands. Presently over 320 optical sensors are installed on the bridge to record data on a continuous basis at 50Hz. Such data contains invaluable information for monitoring the bridge response and condition after each monthly Load Test. In addition, the daily dynamic traffic loading is analysed to detect any sign of degradation in the post tensioned girders. |
