Abstract
Corrosion of steel in structures has become a major cause of structural degradations. Corrosion detection and monitoring are necessary for evaluation of structural service conditions. A novel FBG based sensor for steel corrosion detection and monitoring is developed previously. In this paper the sensor performances are evaluated by comparing to the corrosive rate of rebars in the corrosive environments. The correlation between the wavelength shifts of the sensor and the corrosive depth is established. It is proved that the sensor responses successfully to the occurrence of rebar corrosion, which shows the promising feasibility of applying the sensor for corrosion indicator.
