Abstract:The objective of this report is to provide information on state of the art in structural health monitoring (SHM) and its application to bridges. The most recent trends in SHM with regard to fiber reinforced polymer (FRP) composites are discussed. Different approaches for structural monitoring using vibration-based and acoustic monitoring are examined and methods implemented in each approach are discussed and critically visited. Further discussion focuses on the challenge of monitoring significantly large structures and the reasons to consider frequency and wavelet analysis for damage detection. The report also discusses the technologies used for monitoring one bridge in Tucumcari, New Mexico located on Interstate 40 (I-40).
