Bridge half-joint inspection using acoustic emission technology

Half-joints on bridges present difficulties at the time of carrying out inspections due to the complex geometry of the structure. The areas subjected to the largest amount of stress on half-joints are normally corner areas that are totally non-accessible neither visually nor with other non-destructive inspection methods. Acoustic emission is the recommended inspection method for half-joints following for example the CSC 464 document, which sets out specific requirements for the inspection of bridges in the United Kingdom.

The workshop will present some examples of bridge half-joint inspections considering all practical aspects of the testing operations. Also covered will the variables to consider for the inspection of half-joints with a complex geometry and composite steel/concrete structures.
