Purpose and Background
Since the construction of modern structures, civil engineers have been assisting infrastructure owners with planning, designing, constructing and inspection of their assets using the methodologies that have been developed empirically. Most of these heuristic approaches are based on simplified assumptions. As the infrastructure, especially the bridge inventory, continues to age and becomes a more complicated system its behavior changes. In these cases the traditional methodologies provide a significant challenge to bridge engineers, especially during inspection, load rating and overall safety assessment of “geriatric” bridges. Even though, in some cases the current conventional approaches have met the needs of the owners, there are an increasing number of situations where they have been proved insufficient. In recent years, engineers and bridge owners have started to hire smart technologies and sensing techniques in planning, evaluation, and monitoring of their assets which are mostly geriatric signature bridges that cannot be replaced or their replacement requires a few years during which the bridge has to remain in safe service.
