DISTRIBUTED FIBRE BRAGG GRATING STRAIN SENSING IN REINFORCED CONCRETE STRUCTURAL COMPONENTS

Fiber Bragg grating sensors are of particular interest for distributed sensor applications, where gratings can be addressed using time- and wave-length-division techniques to provide the strain distribution along a structural component. This paper describes the use of a prototype Bragg grating instrumentation system for monitoring the strain at several locations through reinforced concrete beams and decks which are tested to failure. Strain readings are obtained from a number of multiplexed sensors which are bonded to the rebar reinforcement, free floating in the concrete, and embedded in composite materials attached to the concrete.
