Acc *m* /*s* <sup>2</sup> ×10−<sup>5</sup> A composed isolation system has been described and experimentally tested in this paper. For the presentation of experimental results obtained the spectral analysis was used. The images obtained by decomposing of the waves produced as a result of the application of excitation on the structural model were recorded and arranged by wavelength and frequency. The values obtained are presented taking into account the isolated structural element and the recording on main directions of movement. The main maximum values recorded for the motion ampli‐ tude at the level of support pier and superstructure were highlighted. The general trend is of motion mitigation for the superstructure as can be seen in the both transversal and longitudinal direction of movement. A set of random vibrations was chosen in order to move the structure because it simulates the action of a real earthquake.
