Paper Abstract

Intracore Bragg grating sensors have been bonded on to the CFRP tendons of a prestressed concrete girder. The sensors survived both the installation procedure and casting of the concrete beam. Sensor performance is characterized in terms of maximum tensile strength and fatigue behavior. The fiber sensors survived strains of greater than 8000 (mu) (epsilon) and showed no change in either center wavelength or spectral content for 2000 (mu) (epsilon) over 320,000 cycles. The intracore grating sensor was used in a static loading test of the girder to failure and showed excellent stability and durability in comparison with the conventional technology.
