The interesting physical and mechanical properties of granulated rubber as well as its high damping capacity have encouraged the use of this lightweight material in civil engineering applications. Its use has been backed up by relevant studies based on experimental data of clean granulated rubber and rubber/soil mixtures (RSM) indicating improvement of the static and dynamic behavior of geo-structures and foundations. The aim of this work is to investigate the potential beneficial effects of RSM foundation soil on the dynamic soil-foundation-structure interaction response. One dimensional and 2D numerical models were employed to study the dynamic ground response, where the surface layer was replaced by RSM in a limited lateral extend. As for the soil-foundation-structure system response a SDOF has been used for simplicity with a 2D finite element model for both untreated and RSM cases. The modification of the dynamic response of the selected soil profiles is discussed in terms of eigenfrequencies, amplitude amplification, peak ground acceleration and peak cyclic shear strains. Finally, the alteration of the SDOF’s seismic performance is studied and discussed through the computed demand spectra for a specific seismic event.
