Abstract:

The research problem we are trying to solve is the long-term monitoring problem of bridges (e.g., concrete and composite bridges), using multiple modes of sensing technology including fiber optic (BOTDA), optical, and electromagnetic (GPR) sensors. We instrumented a composite bridge (Grist Mill Bridge in Hampden, ME) with sensing textiles. We have developed structural health monitoring algorithms to process the experimental measurement collected from Grist Mill Bridge (Hampden, ME) to study the long-term bridge monitoring problem. We have developed bridge models for extracting the flexural rigidity (EI) of the bridge. We will use it as one of the indicators for long-term health monitoring. We developed a bound approach to determine the structural properties of bridges by using single-point optical measurement.
