Abstract: A FRP-wrapped Balsa wood bridge deck system has been developed and installed in Louisiana. The bridge performance has been evaluated by using live load testing and its long-term performance will be monitored using fiber optic sensors throughout its service. The short-term live load test and plan of the long-term monitoring system is introduced in this paper. Preliminary results from Fiber Optic Sensors (FOS), traditional strain sensors and acoustic emission sensors are analyzed to assess the bridge performance.
