PRESANTATION ABSTRACT:
Management of aging civil infrastructure systems has recently become a grand challenge for engineers. Without proper management of aging civil structures, the failure of these infrastructure systems could have a major economic impact. Structural damage diagnosis is a useful tool for in-service damage detection for structures concerned and is a key element of strategies for condition-based maintenance of aging civil infrastructure. However, the related and yet unsolved question is how to fully utilize the monitored information for assessment of structural safety. Damage prognosis, as a natural extension to damage detection problem, aims to estimate the evolution over time of detected damage and predicted condition, thus allowing the prediction of future performance of deteriorating structures.
In this seminar, a new damage diagnosis based on dynamic perturbation theory will be discussed with several case studies. The influence of measurement uncertainty will be investigated and regularization methods will be introduced to reduce the influence. A reliability-based damage prognosis will then be presented to predict the future performance, estimate the remaining useful life and optimize the maintenance strategy for deteriorating structures during the service life.
