Abstract:

This paper describes the use of embedded fiber optic sensors to monitor the performance of reinforced concrete structures. The fiber optic sensors are capable of measuring vibrations, detecting cracks, locating cracks, measuring overall strains, and possibly detecting acoustic emission events. These simple sensors have been installed in a 6-story reinforced concrete building, an 8 MW reinforced concrete hydroelectric dam, and in a post-tensioned concrete railroad bridge. Preliminary results have been obtained from the sensors in the form of survivability and vibration data.
