摘要
The present invention relates to a steel pipe box girder which is constituted by joining a plurality of unit segments and which is installed in an upper part of the upper part of a bridge pier, and which is coupled to the upper face of the upper flange of the steel part box girder Shaped upper flange reinforcement having two or more rows to allow the prestress to be introduced by the prefraction; A lattice-like upper flange reinforcement rib coupled to the lower face of the upper flange of the steel frame box girder in the throttle direction; A lower flange reinforcement of two or more columns connected to the upper surface of the lower flange of the momentum portion steel box girder in a throttling direction to allow the prestress to be introduced by the prefraction; And a lattice-shaped lower flange reinforcing rib which is coupled to the upper surface of the lower flange of the mandrel portion steel box girder in the direction of the throttle. The present invention also relates to a method of constructing a steel box girder using the same. According to the present invention, the compressive strength is increased at the bridge pier portion and the punching shear crack is suppressed in the high-strength concrete portion at the upper portion of the pier portion, so that the life of the girder is increased and the bending resistance is increased.
