The growing tramway traffic volume, the higher population density in urban areas and the diminishing distance between the tramway track and the structure can be considered to be responsible for increasing vibration nuisance arising from tramway traffic. The vibration velocity level in a building is predicted based on a separate characterization of the source, the wave propagation and the receiver. The numerical results in the time domain are presented as the time histories of the damped amplitudes of the half space vibration at a given distance. In the frequency domain the free-field response is presented as response spectra and the frequency response function of the viscoelastic soil medium. For a practical case study the analytical-experimental approach was used with the theory data combination to assess the actual vibration and calculate the predicted vibration level of the ground and the buildings after a tramway structure reconstruction project.
