| Research Abstract |
To monitor retrofitted sheet on the surface of aging concrete structure, debonding detection for the sheet is studied using advanced optical fiber strain sensor, which is able to measure strain distribution along the whole sensing fiber. At the debonded region, because no stress is transferred from the host structure to the retrofitted sheet, strain on the sheet remains constant. In this study, installation of the sensing fiber into the sheet is developed and experimentally validated to detect debonding using optical fiber strain sensor. Additionally, the measured interfacial stress-strain model is examined.
