摘要

We report the use of fiber Bragg grating (FBG) sensors for strain measurement in a rectangular composite-bonded concrete beam Three FBGs are multiplexed by using a frequency modulated continuous wave (FMCW) technique in the RF-band and embedded at three different locations at the interface between the composite reinforcement and surfaces of the concrete beam specimen. Strain measurements were conducted with the concrete beam specimen subjected to a three-point bending test. The strains measured from the FBG sensors are compared with that from the external bonded strain gauges.
