외부긴장재를 이용한 프리스트레스트 콘크리트 거더교의 성능평가
Performance Evaluation of Prestressed Concrete Girder Bridges by External Tendon
초록
The analysis and design of composite girders prestressed by external tendons involve difficulties related to the position of anchorages and the construction sequences. In this paper, the efficiency of the external tendon profiles and the position of anchorages in examined for the internal and external prestressing of statically indeterminate structures. It is shown that strengthening of a prestressed girder can be accomplished using a variety of methods; bonded external prestressing, tendon replacement and unbonded external prestressing.
