In this paper, the problem of transverse and longitudinal damped vibration of T-type frame was formulated and solved. The vibration energy dissipation in the model occurs as a result of internal, constructional and external damping. Damping in adopted model is a result, of taken into account viscoelastic material of beams that modelled the system, motion resistance in frame supports and influence of medium surrounded the frame. Damped frequencies of vibrations and degree of amplitude decay were calculated. The study also presents eigenvalues of system vibration with respect to changes in damping coefficients and system geometry for selected rigidity of springs.
