FIBER OPTIC SENSORS FOR STRENGTH EVALUATION AND EARLY WARNING OF IMPENDING FAILURE IN STRUCTURAL COMPONENTS

The identification of a fiber optic sensor system has transformed a structural component into a "Smart Structure," according to new findings. Monitoring the deterioration and progressive decay of bridges and buildings, the ability to warn against impending failure, the resulting saving in human lives, and the prevention of sudden economic dislocation is now possible. The research project presented in this report addresses the development and laboratory testing of fiber optic sensor systems for the strain and deformation measurement in civil engineering structures. The research focuses on: 1) fundamental development and characterization of fiber optic strain/stress sensors for civil/structural applications; 2) testing of the developed sensors using large scale laboratory tests; and 3) development of guidelines and criteria for field implementation and usage of the selected fiber optic strain/stress sensors. A comprehensive testing program was designed and conducted in three phases. The work supported in this research program has conclusively demonstrated the merits of using fiber optic sensors for measurement of strain/stress in concrete structures.
