T형 교각머리부 균열원인 분석 및 보수 보강 방안에 관한 연구 = A Study For The Analysis About Crack's Sources and Conservation Method on The T-type Coping Pier

다국어 초록 (Multilingual Abstract)

This paper was compared about the model using loding test with real structure to find the process and the behaviour of crack for loading step.
And using a model test, the present state of crack was analyzed and the reason of crack was defined.
The result of crack in a real coping pier was tensile crack normally.
The source of crack was presumed problems of construction which causes was excessive cover's thickness, the settlement of support of form in construction period, heat of hydration, shrinkage and initial over heavy vehicles etc.
The conservation method of crack in coping pier was recommended by epoxy charge method.
The designated section in coping pier had a problem that don't satisfy demands of specification about shear force.
Therefore, the section needs reinforcement to satisfy specification.
As the method of refrcement, enlargement of cross-section was recommended
