摘要

In order to promote the widespread application of sensor-based structural health monitoring (SHM) systems, complete and standardized systems need to be developed that are adaptable, can immediately begin to monitor the structure’s performance to some degree, and be incorporated into the rehabilitation practices. The combination of fiber reinforced polymer (FRP) laminates and fiber Bragg grating (FBG) strain sensors have the potential to produce such a system for concrete structures. In this work, general processing procedures are developed that efficiently: (1) manage and process the recorded data; (2) ensure the recorded data is accurate and the sensors are working properly; and (3) monitor the limit states of the FRP laminates regardless of their application. The effectiveness of these procedures are then demonstrated through a case study involving the FBG instrumentation of a carbon FRP laminate rehabilitation applied to the Salt Lake Boulevard Bridge for shear strengthening.
