Keywords

Abstract

Fiber Optic Sensors (FOS) offer several promising features for long term Structural Health Monitoring such as distributed sensing capability, durability, stability and immunity to electrical noise. There are different FOS technologies with a wide range of performance metrics that define their suitability for different applications. One of the most widely used fiber optic sensing technologies are point sensors (Fiber Bragg Gratings-FBG). If the data collected with the FBG sensors are analyzed and handled effectively, important information about the behaviour of the structure can be obtained. In this study, a recently developed damage detection method based on strain correlation analysis is employed using strain data collected with FBG sensors. In pursuing these objectives, different damage scenarios have been designed and tested on a 4-span bridge model in the laboratory environment. The efficiency of both FBG sensors and correlation analysis method for detection and localizing damage is explored. It is shown that damage can be clearly identified and localized for most of the cases under investigation. © The Society for Experimental Mechanics, Inc. 2012.
