Classification of Damage Mode of Reinforced Concrete Beams Using Acoustic Emission Technique

Abstract:

Classification of damage modes in reinforced concrete (RC) beams was studied. Acoustic emission (AE) monitoring in conjunction with static test was applied on RC beams. The damage modes were classified by based on the load-deflection curve, the relationship between load and damage modes and the intensity analysis. It can be concluded that six damage modes were identified; namely micro-cracking, localized crack propagation, flexural crack distribution, shear crack formation, damage localization and failure of the beam. The use of intensity chart clearly estimates the zones of the damage mode of the reinforced concrete beams.
