Structural Health Monitoring of Highway Bridges Subjected to Overweight Vehicles, Phase II, Field Deployment

The preliminary research in Phase I of the project demonstrated that the Fiber Bragg Grating (FBG) based sensor for the Structural Health Monitoring (SHM) System is a viable concept with the potential to be implemented and provide valuable data on bridge performance. In Phase II of the project, the FBG-based SHM system will be deployed and operated in the field. The overarching objective of the proposed project is to establish a proven basis for optical-fiber sensor SHM systems on highway bridges with a focus on bridges that may be subjected to overweight vehicles. The proposed SHM system, when completed, is expected to improve the ability of bridge engineers to understand and predict traffic load behavior and bridge load capacity.
