The invention discloses a steel box girder bridge girder. The steel box girder bridge girder comprises a tuned mass damper and a steel box girder accommodating the tuned mass damper. The tuned mass damper is arranged inside the steel box girder for damping the steel box girder. Due to the fact that the tuned mass damper is accommodated inside the steel girder box, high-altitude falling risks of the tuned mass damper and the parts of the tuned mass damper can be avoided, and meanwhile, occupation of external space of the steel box girder can be avoided, and further the steel box girder can be compact in structure and beautiful in appearance. Besides, due to the fact that the tuned mass damper is accommodated inside the steel girder box, turning torque exerted on the steel box girder by the tuned mass damper can be reduced and accordingly the integral stress on the steel box girder can be rationalized. 本发明提出了种用于钢箱梁桥的主梁，其包括：调谐质量阻尼装置以及容纳调谐质量阻尼装置的钢箱梁。调谐质量阻尼装置安装在钢箱梁内，用于对钢箱桥梁减振。由于钢箱梁容纳调谐质量阻尼装置，这样就消除了调谐质量阻尼装置及其部件的高空坠
