Global concrete structure monitoring by utilizing fiber optic sensor
The demand of structure health diagnosis, repair and retrofit is in the increasing tendency year by year. Sustainable structural health monitoring is absolutely needed in order to maintain structure performance and safety economically, specially for repaired and/or retrofitted structure. Though numerous diagnostic technologies with high accuracy have been developed, mostly their sensing capabilities are limited to locally defined defect. In this research, in order to investigate the possibility of fiber optic sensory technology to perform low-cost global structure health monitoring, the verification test on strain and crack in concrete beam was carried out using fiber optical sensory system that can self-rectify expansion and contraction of the optical fiber due to temperature change. The possibility of high reliability and accuracy achievement of the fiber optical sensory system was confirmed by linear expansion coefficient verification test of SS400 steel plate. Furthermore, by observing the experimental test on deformational properties of full rigidity health RC beam and shotcrete-retrofitted RC beam, it became clear that crack deformational monitoring is an effective strategy in detection of concrete structural anomalousness.
