Abstract EN
Acoustic emission (AE) is an important nondestructive evaluation (NDE) technique used in the field of structural engineering for both case local and global monitoring.
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) one story frames were tested under loading cycle and were simultaneously monitored using AE.
The AE test data was analyzed using the relaxation ratio and calm and load ratio method.
Also, the relaxation ratio was dominated with approaching load to 58% of the ultimate load.
In addition three levels of damage using calm and load ratio were distinguished.
The trend of relaxation ratio and calm and load ratio method during loading and unloading showed that these methods are strongly sensitive with cracks growth in RC frame specimens and were able to indicate the levels of damage.
Also, results showed that AE can be considered as a viable method to predict the remaining service life of reinforced concrete.
In addition, with respect to the results obtained from relaxation ratio and, load and calm ratio indicated, a new chart is proposed.
