Features of Monitoring Deformation Processes in Ferro-Concrete Designs with Application of the Reflectometer Method of Recording Signals of Fiber Bragg Gratings

Measurement Techniques Aims and scope

Special features of the use of the reflectometer method of recording signals of fiber Bragg gratings for monitoring deformations of ferro-concrete test beams were studied. Sensitivity to relative elongation of 2.8 dB/10–3 and resolution 30·10–6 in effective range ±2·10–3 were experimentally demonstrated. It is shown that concrete deformations in a surface layer can substantially differ from deformations of the reinforcement rods located within the concrete, and this is explained by the differences between the strength characteristics of concrete and rebar steel.
