Abstract :
Acoustic emission (AE) is an important nondestructive evaluation (NDE) technique used in the field of structural engineering. In this study AE technique with a new approach was employed to investigate the process of fracture formation in reinforced concrete structure. A number of reinforced concrete (RC) frames were tested under cyclic load and were simultaneously monitored using AE. The AE test data using intensity analysis method were analyzed. This is based on calculating two values called the historic index (HI) and severity (Sr). The results showed that HI and Sr increase with increasing of loading cycle and trend of HI and Sr showed that these parameters are able to indicate the levels of damage. Also, the results indicated that AE can be considered as a viable method to investigate the process of fracture formation in reinforced concrete structure.
