초록

본 연구에서는 헤어핀 보강 및 스트럽 보강 선설치앵커의 정적 및 동적 전단하중에 대한 저항강도 평가를 위한 실험을 수행하였다. 보강철근은 D6 이형철근을 사용하였으며 연단거리 120mm의 직경 20mm 앵커에 대해 정적 하중과 1Hz의 편진하중으로 각각 3개의 시험체에 대해 실험을 수행하였다. 헤어핀 보강 앵커는 헤어핀의 덮개가 강도에 직접 영향을 미치는 것으로 확인되었으며, 정적 대비 동적하중에서 강도의 저하는 없는 것으로 평가되었다. 스트럽 보강 앵커는 비보강 앵커에 비해 저항강도의 증가는 미소하였으며 동적하중에 의한 강도는 정적하중에 의한 강도와 거의 같은 값을 보였다.

In this study, an experimental study was performed to evaluate the shear resistance of cast-in-place(CIP) anchors reinforced with hairpin and stirrup bars under static and dynamic loads. The reinforcement was developed using D6 bars, and the anchors were installed with 20mm diameter and 120mm edge distance. Three tests were conducted for each type of reinforced anchor under static and dynamic shear load with a pulsating frequency of 1 Hz, respectively. It was found that the strength of hairpin-reinforced anchor was affected by the concrete cover and the dynamic tests showed no capacity reduction of anchors compared with static tests. The stirrup-reinforced anchor showed little increase of resistance compared with unreinforced anchor and the resistance under dynamic loading showed nearly same strength by static loading.
