Structural health monitoring by periodic NDT. NDT for bridge maintenance
Periodic nondestructive testing (NDT) measurement can facilitate a paradigm shift in quality assurance testing of new construction or in-service inspection of existing bridges. Rather than NDT being specified as a tool for testing the structural integrity of bridge members, it can also be used in the objective analysis of lifecycle benefit/cost or in the performance based monitoring of a constructed structure. Accordingly, any initial NDT measurements will be transformed to a key baseline condition dataset for periodic assessment of structural health. Performance monitoring is achieved by the examination of changes in the data of a surveyed structure over time. This paper describes the concept of periodic NDT for structural health monitoring and gives examples of its application on engineered structures. A special focus lies in the outline of a collaborative benchmark project set up at the FHWA NDE Center using and evaluating state-of-the-art NDT methods for deterioration monitoring of typical concrete structures, such as bridge decks and box girders. The aim is to devise a test protocol for structural health monitoring and asset management of concrete structures by performing periodic baseline NDT measurements.
