摘要
PURPOSE: A girder connection structure of a continuous bridge including a composite form is provided to economically form the continuous bridge without member waste of a truss girder unit and to form the continuous bridge which safely resists to a positive moment and a negative moment. CONSTITUTION: A girder connection structure(100) of a continuous bridge comprises a steel box girder unit(110), a truss girder unit(130), and a connection unit(150). The steel box girder unit comprises a web(111), an upper flange(113), and a lower flange(114), and the upper flange and the lower flange are connected to the upper part and the lower part of the web. The truss girder unit comprises an upper chord(131), a lower chord(132), and a diagonal member(133) and is connected to the steel box girder in a throttle direction. The connection unit connects the steel box girder and the truss girder unit and comprises a stress concentration prevention unit. The stress concentration prevention unit prevents stress concentration from being focused on the upper chord and the lower chord.
