ABSTRACT Geotechnical seismic isolation (GSI) system involves the dynamic interaction between structure and low‐modulus foundation material, such as rubber‐soil mixtures (RSM). Whilst numerical studies have been carried out to demonstrate potential benefits of GSI‐RSM system, experimental research is indispensable for confirming its mechanism effectiveness in reducing structural demand. In this regard, centrifuge modelling with an earthquake shaker under acceleration field 50 g adopted study can mimic actual nonlinear response characteristics RSM subsoil a coupled soil‐foundation‐structure system. This first time performance was examined geotechnical centrifuge. It found that average 40‐50% reduction demand be achieved. The increase both horizontal rotation responses also evidenced. unique augmented rocking reversible highlighted.
