보강강판을 이용한 연속 PSC교량 공법에 관한 연구

초록

It is limited to decrease height or section even by system conversion to indeterminate structure - continuous beam - in existing PSC girder bridges. In this study, the movement of connection is analyzed through actual field test, by increasing stiffness of negative moment area in continuous bridge and developing continuous PSC bridge with embedded steel plate, that can overcome the demerit of existing connection. As a result, It is confirmed that the body unification of the connection is being realized and maintained. Moreover, the height of a span is suggested in continuous PSC girder bridge with embedded steel plate by computational analysis.
