Using Acoustic Emission Technique for Monitoring Real-time Fracture Behavior within Reinforced Concrete Structure Element under Load Test
Stress waves emitted by defect formation or material failure within reinforced concrete (RC)can be complicated in propagation, wave form and frequency modes. However, the acoustic performance can indicate many invisible structural behaviors under loading. In this paper,Acoustic Emission (AE) technique was introduced to digitally record the emitted stress waves in RC-slab and RC-beam specimens during the load tests. Different fracture behaviors, such as Kaiser effect, crack-control mechanism and stress re-distribution, will be evaluated by using these records. Beside the experiment, further application will be discussed.
