AE Monitoring of Boghall concrete bridge, Scottish Borders
During the last decades, the understanding and use of the Acoustic Emission (AE) technique has been developed and progressed, posing the basis for its application to real civil engineering structures. Among the latter, bridges represent a fundamental category. Attempts to apply the AE method on bridges started in 1971, initially focusing on steel bridges. The successful results obtained on steel structures opened the way to further investigation on the feasibility of the AE technique to concrete bridges. Recently, several examples of AE study on concrete structures have been carried out, and there have been a variety of approaches on how to carry out an AE investigation on a bridge. This variety is both in terms of equipment used, and type of data that were collected and analysed. This paper focuses on the latter issue and illustrates four different ways to collect and analyse data that can provide information about the structure under study. The different methods include an attenuation study, a noise study, an AE source location and a b-value analysis. The data presented were collected on a concrete bridge in Scotland.
