This paper presents a recent research advance on the development of a novel adaptive seismic isolation system to be used in seismic protection of civil structures. A highly-adjustable laminated magneto-rheological elastomer (MRE) base isolator was developed and experimental results show that the prototypical MRE base isolator provides amazing increase of lateral stiffness up to1630%. To facilitate the structural control development using such adaptive MRE base isolator, an analytical model was developed to simulate its behaviors. Comparison between the analytical model and experimental data proves the effectiveness of such model in reproducing the behavior of MRE base isolator.
