This paper presents the intensity crack zones of reinforced concrete (RC) beam under monotonic loading in conjunction with acoustic emission (AE) monitoring. Five RC beam size 200 mm x 300 mm x 1500 mm were prepared and tested. Due to similar pattern in term of the crack pattern and the analysis, only one beam was presented in this paper. The intensity crack zones were performed by mean of historic and severity indices at sensor 6 (CH6) and sensor 7 (CH7). The plot in the intensity crack zone was based on the crack mode performed during testing. As a result, the progression of the crack was well-matched with the plots in the intensity crack zones. In a nutshell, the data obtained from the AE signal and analyse using intensity analysis, it can be used to classify damage in the RC beam.
