Structural health monitoring of offshore structures using Fiber Bragg gratings

Over the last few years, optical fiber sensors have seen an increased acceptance as well as a

widespread use for structural sensing and monitoring in civil engineering. FBG sensors have

all the advantages attributed to the optical fibers. In addition, they can be easily multiplexed

in a serial fashion along a single fiber. The experimental program includes testing of three

two-way reinforced concrete slabs. One normal strength concrete slab (NS) and two high

strength concrete slabs (HS) will be selected for the experimental investigation. Two sets of

FBG and ESG strain sensors will be mounted on tensile rebars. Another FBG sensor will be

embedded inside concrete slabs. All tests will be carried out using a closed-loop (MTS) testing

machine. The load will be applied by means of a hydraulic actuator. During testing, the slabs…
