Abstract

According to the development of ultra-high performance concrete (UHPC), its mechanical performance have been known as superior than normal and/or high performance concrete. However, its construction and structural safety must have studied with revisions and supplements. In this study, tests have been performed on UHPC precast segment joint with different levels of joint types and lateral forces under direct shear. From the results of the experimental tests, it can be concluded that the properties of the referred joints are significant for the resistance of shear behavior, and the increase of lateral force in these joints may suggest as critical lateral stress on that behavior.

초고성능콘크리트(UHPC)의 개발은 재료 역학적 특성면에서 기존의 일반 및 고성능 콘크리트에 비해 월등한 역학적 성능을 발휘하는 것으로 인식되고 있으나, 이에 관한 시공성 및 구조적 안전성에 대해서는 향후 많은 수정 및 보완 작업을 필요로 함이 예상되어진다. 이 연구에서는 UHPC를 적용한 프리캐스트 접합부의 전단 거동 특성의 분석을 위해 접합부 사이에 전단키를 설치한 경우의 접합 방식 및 횡구속 응력에 따른 전단 거동 특성 실험을 수행하였다. 실험 결과 에폭시 접합을 이용한 UHPC 접합의 경우가 현장 타설을 모사한 일체 타설의 경우보다 파괴 하중 및 전단 저항 응력면에서 우수함을 보였고, 횡구속 응력의 증가에 의해 전단 응력은 증가되지만, 횡구속 응력과 전단 응력 사이의 상호 효과에 따른 최적 임계 횡구속 응력이 존재하고 있음을 제시할 수 있었다.
