H-beams set up between columns are widely used to support building slabs. However, H-beams have fixed joints and the bending moment at both ends of the beam under uniformly distributed load is twice as great as the moment at its center. Because beam design is based on ultimate moment, its depth gets to be larger, which leads to the problem of smaller available space on each floor. If the ends of H-beam which are vulnerable to ultimate bending moment are additionally reinforced, beam design based on the bending moment at beam center is feasible. In this study, 4 specimens were fabricated for structural experiment with variables of the purpose of end-reinforcing steel plates, bar reinforcement and load transfer method in order to analyze the structural performance of end-reinforced steel frame beams (hereinafter Eco-girder system).
