Analysis of the AE signals parameter at the critical area on the concrete beam

This paper enquires the utilization of acoustic emission (AE) to identify the nature of damage such as tensile cracks and shear movements at the critical zone within a structure. The AE parameters were involved in this research are Amplitude, Rise Time and Average Frequency. Some experimental works were performed with the scale of the beam (150 × 250 × 1900 mm) and AE data was captured then analyse by post-test analysis. Eventually, the acoustic emission analysis was successfully identifying the cracks movement accordance to the real observation during the loading cycle.
