Resum
The use of Optical Backscatter Reflectometer (OBR) as a distributed fiber optic system to measure strain and detect cracking in concrete structures is investigated. A laboratory experience in a concrete slab is first presented and after this pilot test, a full-scale bridge load test was used to investigate the effectiveness of the OBR technology monitoring system when applied to real structures. The bridge monitoring consisted of the installation of 100m of optic fiber in the soffit of the prefa...
