Acoustic Emission Characteristics of RC Beams retrofitted by Carbon Fiber Reinforced Polymer
CFRP 보강겹수에 따른 천근콘크리트보의 음향방출특성
Abstract
In recent years, carbon fiber reinforced polymer(CFRP) has been widely used for reinforcement of damaged concrete structures. However, the fundamental mechanisms of load transfer and load-resistance for reinforced concrete beams retrofitted by CFRP are not fully understood. Acoustic emission(AE) technique was used to evaluate the characteristics of damage progress and the failure mechanism of reinforced concrete beams retrofitted by CFRP. In this study, three-paint-bending test has been carried out to investigate the AE characteristics of four specimens. The results show that the AE technique is a valuable tool to study the failure mechanism of reinforced concrete beams retrofitted by CFRP.
