In this paper, a damage detection technique for flexural structure using strain measurements from long-gage fibre Bragg grating (FBG) sensors for structural health monitoring (SHM) was developed. An experimental investigation of flexural beams based on distributed long-gage fibre optic sensors was carried out. A method of damage detection for flexural structure from distributed dynamic strain measurements was proposed and verified. Furthermore, a parameter study of the damage detection index proposed by author by means of analysis of experimental data was performed and the possible range for practical utility of the damage detection method was confirmed here. The above damage detection technique could be applied to the health monitoring of bridge and other flexural structures. |
