PURPOSE: A double T-girder with a steel reinforcement beam is provided to remarkably improve structural performance by increasing bending rigidity without increasing the height of the girder. CONSTITUTION: A double T-girder(1) with a steel reinforcement beam comprises an upper flange(10), two webs(20), and steel reinforcement beams(30). The two webs are separated from each other in the width direction of the girder and are integrally formed in the upper flange. The steel reinforcement beams are extended in the longitudinal direction of the girder, and the flanges thereof are buried in the bottom surface of the upper flange between the webs to reinforce the bending rigidity of the girder. |
