Abstract:The damage in concrete structures generally starts with rnicrocracking and thus it is important to find and explore these microcracks in concrete in order to ensure appropriate safety and serviceability. The purpose of the present study is to identify the damage characteristics of concrete structures due to cracking by employing the acoustic emission techniques. A comprehensive experimental study has been done. The cracking damages under tensile and flexural loadings have been identified and the bond damage between steel and concrete have been also characterized. It is seen that the amplitudes and energy level of Acoustic Emission (AE) events are found to be relatively small for bond cracking damages and large for tensile cracking damages. The present study provides useful data which can be used to identify the various types of cracking damages in concrete structures. This will allow efficient safety management of concrete structures through monitoring of internal cracking based on acoustic emission.
