Paper Abstract

In preparation for the construction of the Rollinsford bridge in Rollinsford, NH, a test specimen of the bridge deck was constructed at UNH. The testing of this slab was also used as a trial run for an experimental distributed strain sensor. The slab was equipped for strain measurement using a Brillouin-scattering based fibre optic sensor, along with more conventional strain and displacement gauges. Some of the results and the difficulties encountered during this investigation will be presented. Additionally, further investigations into measuring strain on structural members done in preparation for instrumenting the actual bridge are presented.
