The present invention provides a longitudinal segmental girder comprising: a PSC U-shaped girder with a tilted abdominal unit and a flange connecting the tilted abdominal unit; or a closure box girder. The girder has a first segment and a second segment because the flange is vertically divided into two parts. On the combining surface where the first and second segments are combined, shear keys are respectively formed and combined to each other and epoxy is spread for being integrated. The PSC girder is vertically divided and assembled for minimizing construction weight and minimizes the weight of the girder during construction, thereby securing structural benefits of a box cross section and at the same time, economic feasibility of the cross section of the tilted abdominal unit for being very effectively applied to the span between major axes. |
