| Abstract: | Fiber Bragg grating (FBG) sensors were embedded into the pre-stressed concrete beam of Hulan river bridge. Internal strains of the concrete beam were determined during the stressing process. FBG sensors show the advantages of strong surviving capability and long service life over conventional electrical strain gauge in experiments. The results indicate that FBG sensors have the potentials to forge a flexible framework for the monitoring system. |
| Keywords: | strain fiber Bragg grating monitor |
