000009834 520__ $$2eng$$aBase isolation is nowadays widely considered as an effective strategy to protect structures subject to seismic excitations. However, it has been shown that, in the case of seismic excitations with high energy content at low frequencies, i.e. a near-fault event or a seismic wave propagating itself through alluvial soil, isolation bearings may undergo gross deformations. Observing that the response of base-isolated (BI) systems is dominated by the first-modal contribution and that Tuned Mass Damping (TMD) is able to reduce the fundamental vibration mode, a new idea of combining both properties into a unique system (BI&TMD) was proposed and investigated by Palazzo and Petti. A benchmark structure in which the non-linear response of isolation devices (elastomeric and friction pendulum) is explicitly considered has been recently defined. By using this model, this paper aims to investigate the non-linear behaviour of the benchmark isolated structure when a mass damping system is applied on the isolation layer, in order to study the effectiveness of this strategy in reducing the seismic response of the isolation layer.
