Analysis of different installation techniques: (a) Strain profiles along reinforcement (tight-buffered fiber, glue). (b) Strain profiles inside concrete (BRUsens V3, cable ties). (c) Strain profiles along surface (tight-buffered fiber, glue). (d) Curvature values derived from DFOS strains and theoretical model. (e) Displacement curves calculated from DFOS strains, measured by LVDT and theoretical model.
