Abstract:
A concrete girder includes a pair of ultra high performance concrete (UHPC) side form members, each having a lower flange and a web perpendicular thereto, extending in the longitudinal direction and being prepared with UHPC by using a precast, the pair of UHPC side form members being disposed in parallel so that lateral side surfaces of the lower flanges are successively positioned; and concrete placed in a space between the pair of UHPC side form members so that the placed concrete is integrated with the pair of UHPC side form members to form both traverse side surfaces thereof and the lower flange forms a lower flange thereof.
