CFRP로 전단보강된 철근콘크리트 보에서 음향방출 특성을 이용한 균열 위치추정

Acoustic Emission Technique for Crack Source Location of Reinforced Concrete Beams Strengthened in Shear with CFRP

This study was conducted to develop the crack location technique for CFRP reinforced concrete beam using AE method. To experimentally prove the crack source location made of four reinforced concrete beams strengthened in shear with CFRP. The results compared the real cracking location with the source location has perceived by AE monitoring, before it is appeared the primary crack by visual observation. So, This study used by a basic data in constructing the system of the failure warning at application.
