Structural Health Monitoring of Bridges Using Acoustic Emission Technology

摘要：

Bridges are important part of societys infrastructure and reliable methods are necessary to monitor them and ensure their safety and efficiency.Bridges deteriorate with age and early detection of damage helps in prolonging the lives and prevent catastrophic failures.Most bridges still in used today were built decades ago and are now subjected to changes in load patterns,which can cause localized distress and if not corrected can result in bridge failure.In the past,monitoring of structures was usually done by means of visual inspection and tapping of the structures using a small hammer.Recent advancements of sensors and information technologies have resulted in new ways of monitoring the performance of structures.This paper briefly describes the current technologies used in bridge structures condition monitoring with its prime focus in the application of acoustic emission (AE) technology in the monitoring of bridge structures and its challenges.
