Аннотация: 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 dПоказать полностьюeformations 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. © 2017, Springer Science+Business Media, LLC, part of Springer Nature.
