Abstract
Reinforced concrete (RC) has been facing several types of damage mechanism during their lifetime. The types of
common defects in concrete structures are crack formation, corrosion, scalling and etc. Therefore a non destructive
evaluation method such as Acoustic Emission (AE) is required for assessing the condition of the RC structures. AE
testing in RC structures shows great potential in monitoring and assessing the health conditions of structures. AE is
used as a tool to detect, identify, locate and quantify a variety of damage mechanism. Apart from an extensive
literature studies had been done, this research had covered some tested of RC structures in locally and globally. A
wide range of analysis had been explored in order to evaluate and quantify damage to enhance the research platform
in Structural Health Monitoring (SHM) area. The evaluation methods that had been explored were acoustic wave
velocity, Moment Tensor analysis (MTA) and intensity analysis. As a summary this research had been a triumphant
study and the continuity of this research as shown in successfulness in Exploratory Research Grant Scheme (ERGS)
application (RMII0,000). Apart from that few publications has been published with the financial support from this
USM Short term grant.
