Abstract: Fiber Reinforced Polymer Composites offer long life in infrastructure due to their corrosion resistance and durability. Unfortunately, there are no 75-year old FRP composite bridges out there to convince everyone the long life. It is the two-year anniversary of the installation of the Fiber Reinforced Polymer (FRP) composite bridge deck a rural community in Morgan County, TN [1]. This paper describes the structural health of the bridge using visual inspection and data from the sensors. Two Structural Health Monitoring (SHM) systems were installed. A continuous monitoring system using discrete wireless sensors (magnetometers, accelerometers, absolute deflection, and temperature) and an associated data collection and communication system. The second system is a distributed fiber optic sensing (DFOS) system, using high definition fiber optic sensors (HD-FOS) and fiber Bragg (FBG) sensors attached to the FRP panel. The wealth of data from the SHM system installed on the bridge provided comparison data from the initial installation to the two- year anniversary. Response of the bridge to static and moving loads from heavy dump truck are included with results from continuous high-density fiber optic data. Using data from the wireless environmental monitoring module to evaluate coupled thermal and mechanical response monitoring of bridges from this project can lead to achieving smart health monitoring bridge systems, on-demand, and at low cost.
