Vibration control of structures includes passive, semi-active, active and hybrid control. Tuned mass dampers (TMDs) as one of the most effective methods for passive control of structures are in the focus of researches in recent years. In this paper, 10-story special truss moment frame (STMF) in the state without buckling restrained braces (BRBs), with the presence of BRBs, as well as the addition of TMDs on the structure equipped with BRBs, has been investigated under different earthquakes, regardless of the effect of the site. In this regard, TMDs with a mass ratio of 2% of the mass of the structure have been installed at six points on the roof of the structure. The results suggest the appropriate performance of TMDs and BRBs together. The amount of improvement in the results compared to the case without BRBs in structure is 27.95%. The effect of adding TMDs in reducing the vibrations of the structure is almost the same as the case with BRBs.
