Abstract
The prediction models for the ground–borne vibrations and irregular buildings (IB) structure dynamic response due to traffic means have been introduced. For the free–field dynamic response at the distance (e.g. from railway track) and dynamic response of IB in the calculation procedures are described in this paper. The numerical model of the soils is modelled as a viscoelastic half-space. This model is used both for evaluation of the track–soil interaction forces as well as for prediction of the ground–borne vibrations. The numerical results in time domain are presented as the time histories damped amplitudes of the half-space vibration at the distance. In presented frequency domain free–field response is calculated via response spectra and frequency response function (FRF) of the viscoelastic soil medium. In the next step this functions are applied for building structure dynamic response calculation due to railway traffic (case study) via relevant computational building structure model.
