Monitoring an interstate highway bridge with a built-in fiber-optic sensor system
An optical fiber monitoring system was designed and built into one span of the five span high performance prestressed concrete I-10 Bridge over University in Las Cruces, NM. A total of 72 long-gage (2 m long) deformation sensors, along with 36 thermocouples were embedded in the prestressed concrete girders. Sensors were installed along the bottom and top flanges, at mid-span and quarter spans. Pairs of crossed sensors in a rosette configuration were embedded in the webs at the supports. The embedded sensors measured temperature and deformations at the supports, quarter spans, and mid-span. Data was collected from the start of construction thru service. Collected data was analyzed to evaluate the prestress losses and cambers in the girders. Actual losses and camber were compared to the losses and camber predicted using available code methods. The project was funded by the New Mexico DOT and the FHWA under the Innovative Bridge Construction Program.
