AN EXPERIMENTAL STUDY ON STRAIN DISTRIBUTION OF BONDED JOINT UISNG OPTICAL FIBER SENSOR

초록

The strain distribution of the bonded T joint was measured using the attached optical fiber and the distributed fiber sensor system based on BOCDA method. The strain near the adhesive fillet was changed sharply and had the maximum value at the corner. The full section of T joint was effectually monitored. The measurement of the strain distribution in this experiment can be used to verify the joint design during the vertical load test and to detect the fracture at the corner.
