The paper presents the formulation and solution of Γ-type frame damping vibration. The physical system model takes into account the energy dissipation of the vibrating frame due to the internal vibration damping of the viscoelastic frame material and the constructional damping in the place of frame bolt support. As the results of the problem solution, the damping and system geometry effects on the first frame eigenvalue (damped frequencies and coefficients of amplitude decay factor) were presented.
