Abstract

Acoustic emission (AE) based-methodology was developed as a non-invasive means for monitoring and evaluating the influence of corrosion on the structural behaviour of steel reinforced concrete (RC) beams. Analysis of the AE data reveals distinguishable trends for RA value and average frequency (AF) registered for different corrosion levels, respectively. Moreover, the index of damage (ID) derived from the AE energy parameters obtained during the first stage of damage was found to be useful as an indicator for evaluating the extent of corrosion damage of the specimens at initial loadings. To provide a practical application of AE toward life span estimation of corroded beam specimen, a Weibull damage function was also introduced to estimate the remaining flexural capacity of the beam specimens.
