Abstract
Fiber Optic Bragg Grating (FOBG) sensor was tested on large scale concrete beams for measurement of strain due to flexural deformations. The sensor, which has recently been developed at the United Technologies Research Center (UTRC) for monitoring of strain in structural composites, was tested with the objective of direct and quantitative measurement of load induced strain. The experimental results showed that the FOBG sensor can be used for monitoring strain in concrete structures through remote sensing. A number of issues such as sensor bonding to structure, sensor placement, sensor arrangement (embedded or exposed), and instrumentation on large concrete structures were addressed in this study.
