Damage Source Identification of Reinforced Concrete Structure Using Acoustic Emission Technique
Acoustic emission (AE) technique is one of the nondestructive evaluation (NDE) techniques that have been considered as the prime candidate for structural health and damage monitoring in loaded structures. This technique was employed for investigation process of damage in reinforced concrete (RC) frame specimens. A number of reinforced concrete RC frames were tested under loading cycle and were ...
متن کاملAcoustic Emission Monitoring of Multicell Reinforced Concrete Box Girders Subjected to Torsion
Reinforced concrete (RC) box girders are a common structural member for road bridges in modern construction. The hollow cross-section of a box girder is ideal in carrying eccentric loads or torques introduced by skew supports. This study employed acoustic emission (AE) monitoring on multicell RC box girder specimens subjected to laboratory-based torsion loading. Three multicell box girder speci...
متن کاملMonitoring Damage Using Acoustic Emission Source Location and Computational Geometry in Reinforced Concrete Beams
Non-destructive testing in reinforced concrete (RC) for damage detection is still limited to date. In monitoring the damage in RC, 18 beam specimens with varying water cement ratios and reinforcements were casted and tested using a four-point bending test. Repeated step loads were designed and at each step load acoustic emission (AE) signals were recorded and processed to obtain the acoustic em...
متن کاملAcoustic Emission for Monitoring Damage Ac- cumulation in Reinforced Concrete Structures
Acoustic emission (AE) analysis is a good tool for monitoring the formation of damage in a structure. A loading experiment with a reinforced concrete beam was carried out and the obtained AE data were analyzed in order to get information about the internal processes of deterioration. Events could be localized, and their estimated source coordinates coincide with the developing crack planes. The...
متن کاملFire Damage Assessment of Reinforced Concrete Structures Using Fuzzy Theory
Once a reinforced concrete (RC) structure is damaged by fire, the fire damage assessment should proceed to take appropriate post-fire actions, including the decision-making of whether it can be repaired for reuse or not. Since the assessment results of current fire damage diagnosis methods, however, highly depend on the subjective judgment of inspectors, it is hard to ensure their objectiveness...
