Steel box girder has not only an excellent constructability but is also a lightweight structure. Compression flanges of steel box girder under negative moment need stiffeners to increase buckling strength, thereby increasing the construction cost. In this study, compression flanges using trapezoidally bended plates were investigated to replace existing flat flanges.
