Paper Abstract

In this paper, a structural behavior monitoring (SBM) based maintenance methodology is conceptualized to combine the advantages of visual inspection and state-of-the-art instrumentation. It depends on the data taken from the instrumentation in the decision-making process of infrastructure maintenance schedule. As such, SBM must address key factors such as the ease and cost effectiveness of sensor deployment, reliability in measurement, and quality of measured data. SBM is focused on major failure mechanisms in structural engineering, and use of advanced distributed sensors for behavior-related or mission critical data collection from representative 'hot spot' areas or part of a structure that will likely experience damage or significant deterioration. SBM has several unique attributes such as damage transfer mechanisms in sensor designs, coupled local and global measurements, multi-parameter monitoring for system behaviors, and integrated monitoring and mitigation strategies. They are discussed and illustrated with examples in this paper. Example structural behaviors include, but not limited to, concrete crack and spalling, steel yielding and corrosion, debonding, member buckling, foundation scour, and fatigue.
