Abstract

Corrosion of steel reinforcement in the reinforced concrete (RC) members contribute to structural damage and failure. This study proposes a damage classification method for corroded reinforced concrete (RC) beams subjected to flexural loading by linear discriminant analysis (LDA) of acoustic emission (AE) data. The structural behavior of RC beam specimens induced with varying steel corrosion levels was evaluated by AE monitoring during the flexural load test. Analysis of primary AE data, RA value (ratio of rise time to amplitude of the waveforms) could be correlated and used to classify the fracture type. It was found that the proposed LDA could achieve good accuracy in damage classification of corroded RC beams.
