| Abstract: | Fiber Bragg grating(FBG) strain sensors are calibrated and embedded into the reinforced concrete beams. Operating techniques and protective methods suitable for civil engineering structures are presented. With FBG sensors, internal strains of the reinforced concrete are determined in lab and on construction site. FBG sensors are advantageous with respect to the absolute value measurement and long service life over the conventional electrical strain gauge in experiments. The results indicate that it is possible to build a structural health monitoring system based on fiber optic sensors. |
