Abstract
We report the feasibility of an OFDR system that is capable of high-speed distributed strain measurement for real-time health monitoring of concrete structures. When a concrete column was shaken by a seismic wave, the strain amplitude changes and frequency response were measured with a data comparison between the OFDR and strain gauge.
