Abstract
Fatigue crack classification on reinforced concrete beam is significantly vital. Acoustic emission (AE) signals were analysed to identify the classes of reinforced concrete (RC) beam corresponding to a specific crack mode. Third point loading fatigue test was carried out based on various range of maximum fatigue loading. The classification of crack for each phase of loading allowed the identification of the cracks mode of the beam namely tensile crack and shear crack. Average frequency and RA value were computed corresponding to channel basis and located event of AE signal and used to classify fatigue crack. The relationship between average frequency and RA value indicated clear trend with respect to crack classifications. Using this relationship trend, estimation of the crack monitoring can be made.
