The possibility of using a response spectra method (RSM) for the calculation of structures with mass dampers (MD) is considered. It is shown that the Guide Lines SP 14.13330.2014 allows us to take into account the MD behavior and estimate its efficiency. However, it is impossible to optimize damping in the mass damper elements. To take into account the damping RSM, including amendments to the damping and the mode correlation, may be modified. In this case, satisfactory results are obtained when the relative weight of MD less than 0.7 and the construction damping of less than 0.3 (15% of the critical value). For the great mass of the MD optimum damping is more than 20% of the critical, and there is a need to consider the effect of modal damping.
