Abstract
This monitoring work presents the results of the field project, Acoustic Emission (AE) was used as a monitoring technique to detect and locate cracks and to monitor its propagation from the crosshead of the bridge. The advantage compared with other techniques is that the signal was generated in the material itself and will be recording the process of damage throughout the entire load without destroyed on the bridge structure. AE waves are high-frequency stress waves generated by the rapid release of redistribution energy from material localized sources, such as crack initiation and growth. The high sensitivity to crack growth to ability detect sources, passive nature and the possibility to perform real-time monitoring are some of the interesting features of the AE techniques. After the monitoring work, using AE wave signals including parameters such as AE amplitude, rise time, and average frequency, the crack pattern at the crosshead of the bridge will be identified according to the type of crack process, active crack, and crack classification.
