Fiber optic sensing for structural health monitoring

Abstract

The subject of structural health monitoring (SHM) is emerging as an increasingly important methodology in evaluating the ‘health’ of a structure by assessing the level of deterioration and remaining service life of civil infrastructure systems. Successful field implementation of SHM has not been widely achieved and depends on overcoming several roadblocks, including the development and demonstration of SHM sensors that have long term stability and reliability and validation of the capability of the SHM systems in terms of the probability of detection of flaws.
