Vibration based condition monitoring: A review

Vibration based condition monitoring refers to the use of in situ non-destructive sensing and analysis of system characteristics - in the time, frequency or modal domains - for the purpose of detecting changes, which may indicate damage or degradation. In the field of civil engineering, monitoring systems have the potential to facilitate the more economical management and maintenance of modern infrastructure. This paper reviews the state of the art in vibration based condition monitoring with particular emphasis on structural engineering applications.
