dc.description.abstract반두께 프리캐스트 콘크리트 바닥판의 적용이 증가함에 따라, 프리캐스트 구조물 간의 연결에 대한 연구가 증가하고 있다. 또한, 프리캐스트 패널을 갖는 합성바닥판에서 패널간에는 횡방향 이음부의 연속적인 거동이 요구된다. 이 논문에서는 루프이음 방식을 적용하여 교축방향 패널과패널사이의 이음부에 구조적 연속성과 성능을 평가하였다. 실험결과로부터 바닥판의 연속성 확보를 위한 루프철근 이음부의 휨강도 및 균열제어의 연속성을 확인하였다. 실험결과 루프이음 철근 간격을 좁게 한 경우의 휨강도가 1.52배 증진되는 효과를 보였다. 또한, 루프이음부에 횡방향 철근은 균열제어에 매우 효율적임을 확인하였다.-
dc.description.abstractAs the half-depth precast concrete decks are increasingly applied to the construction sites, researches on connection details have been increased. For design of concrete bridge deck with half-depth precast panels, it is required to provide appropriate details of transverse loop joints between panels. In this paper, the structural performance of precast decks was evaluated to investigate continuity of the proposed loop joint details. From the results, the validity of the joints for the continuity of deck was observed in the aspect of flexural strength and crack control. The ultimate strength increased 1.52 times as the reinforcement spacing in the joint was reduced. In terms of crack control, direct crack width calculation for the loop joint showed appropriate results comparing with measured crack width.-
