Реферат:	eng: 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 center dot 10(-6) in effective range +/- 2 center dot 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.
