The aim of the article is to estimate the damping properties of a steel structural element equipped with a viscoelastic layer (VS) in the base node. The viscoelastic material has a good energy dissipation properties, has a relatively high strength, and its properties remain unchanged over the time. However, its damping properties may vary for different temperatures and excitation frequencies. In this work, the effect of frequency was examined, but the influence of temperature was omitted. For the selected viscoelastic material, laboratory tests were carried out to estimate its ability to dissipate energy in various load states. The viscoelastic material was then used as a washer in the joint connecting the steel element to the concrete base. The dynamic test and numerical analysis carried out for the structure with the viscoelastic layer allow estimation of some damping parameters for the considered system.
