abstract
Structural health monitoring of civil engineering structures by means of fiber optic sensors is feasible both for static and dynamic analysis cases. The use of Bragg grating sensors for monitoring of deformations in concrete structures has been extensively investigated at Ghent University in the framework of a PhD study in 2001. Hereby, both laboratory and in situ test cases were considered. In the current investigation static tests on concrete and steel specimens, which have been instrumented with fiber optic Bragg grating sensors are conducted. The test specimens are those as originally manufactured and tested in 2000. Hence, the same tests are repeated on the original specimens after almost 10 years and results are compared. Furthermore, a simple dynamic tests was performed on one of the steel bar specimens, to see its dynamic response and the feasibility of direct measurement of modal strains by means of the integrated Bragg grating. The obtained test results demonstrate the feasibility of optical strain sensors for both static and dynamic measurements, in this particular setting of specimens equipped with Bragg gratings 10 years ago. It was however noted that the measurement data was not completely consistent. As no systematic trend in less consistent measurements could be found, and as it was not possible for the given test setting to make a clear distinction between influencing parameters, no sound conclusions could be drawn on the basis of the reported investigation.
