Acoustic emission for monitoring damage accumulation in reinforced concrete structures
Acoustic emission (AE) analysis is a good tool for monitoring the formation of damage in a structure. A loading experiment with a reinforced concrete beam was carried out and the obtained AE data were analyzed in order to get information about the internal processes of deterioration. Events could be localized, and their estimated source coordinates coincide with the developing crack planes. The occurence in time and the magnitude distribution of AE signals contain information about the fracture processes. The signal rate for small events with a low maximum amplitude was compared with the occurence of signals with a high one. A qualitative interpretation of the magnitude-frequency distribution allowed to distinguish between early microcracking, crack formation and crack growing. Further work is necessary to derive reliable parameters for estimating the damage progress.
