Abstract: Shear-induced damage in concrete beams subjected to bending has been studied in recent years both experimentally and by modeling. Different conclusions which sometimes contradict each other about the existence of shear-induced damage in experimental tests can be found from previous studies on this topic. We propose in this study to assess the existence of shear (or Mode II) damage by means of Acoustic Emission (AE) technique. After filtering the raw data, the usual RA-AF classification process based on RILEM TC 212-ACD is used to determine the proportion of each type of damage (Mode I and Mode II) and the results tend to show that a large proportion of AE signals are associated with mode I damage.
