철근 콘크리트 구조물의 비파괴시험에서 압축강도 추정에 미치는 철근의 영향

There are many non-destructive testing have been used for quality control and inference the strength of concrete structureand that case, many influence factors have been studied. One of that factors, this study was aimed for analyzing the influence of steel bar in reinforced concrete on the non-destructive testing by Schumidt hammer and ultrasonic pulse velocity. conclusively the Schumidt hammer did not affected by steel bar, but ultrasonic pulse velocity was affected by linear hoop and main steel bar group in measurment portion.
