Abstract

Failures of segmental bridges have been attributed to the inadequate joint connection techniques, which led to corrosion of the post-tensioned tendons connecting the segmental joints. The principal objective of this study is to evaluate the performances of the in-situ cast joint and epoxy applied shear key joints as a function of shear and ultimate strengths. Furthermore, shear behavior and strength of shear key joints in ultra high performance precasted concrete segmental bridges are experimentally evaluated to understand its shear failure behavior. The test parameters of shear key shape and type, load-displacement relations, cracking behavior, concrete strength, and fracture modes are considered in the study. Also, several parameters which influence the mechanical behavior of the shear key joint are analyzed. Based on the study results, the optimal shear key shape and joint type are proposed for the joint design and analysis guidelines.

세그멘탈 교량의 파괴는 부적절한 접합에 의해 파괴를 일으키게 되는데 이는 세그멘탈 접합부를 가로지르는 횡방향 텐던의 부식을 야기하게 된다. 이 연구에서는 현장 타설 접합 및 에폭시 접합 조건에 따른 초고성능 프리캐스트 콘크리트 접합부에서의 전단키 거동을 전단 및 극한거동 측면에서 평가하였다. 또한, PC 세그멘탈 교량 접합부의 전단 거동을 파악하기 위하여 전단키 접합부의 전단 거동과 전단강도 특성을 실험적으로 연구하였다. 이 연구를 통하여 접합부 형상에 따른 하중-변위 관계, 균열 거동, 파괴 모드, 전단 강도 등을 구명하고, 접합부의 역학적 거동에 영향을 미치는 여러 인자들에 대해 분석한다. 또한 이로부터 최적의 접합부 형상을 도출하고, 이에 따른 최적의 접합 방식을 검토함으로서 접합부 설계의 지침과 해석의 근거를 제시하도록 한다.
