Acoustic emission technique as a tool for structural health monitoring of bridge cables

Résumé

In this work, the use of acoustic emission as a NDT technique for detecting wire breaks and corrosion in bridge cables is reviewed. Wire failure and corrosion in cables, detected using AE, will be discussed either from detection and/or structural health monitoring points of view. The health monitoring technique of bridge cables (cable-stayed, suspension, pre-stressed) is being carried out at LCPC using an acoustic emission derived technique called the CASC system. This technique is based on the detection of wire breaks arising during monitoring and has been used on various bridges since the 70's with success. A summary of this technique will be presented below.
