Abstract

In this research work a seismic base isolation system is studied. The analysed seismic base isolation system is realized by high damping hybrid seismic isolators. This isolator is obtained by the assembly in series of lead rubber bearing and a friction slider characterized by strong friction coefficient. The nonlinear dynamic behaviour is studied by analyzing the proper hysteretic cycles of the base isolation device. The analyzed base isolation device is intended to be able to work under the effects of strong dynamic and seismic events, whereas strong dynamic events are considered those characterized by high intensity and/or high frequency content. In this regard a nonlinear dynamic analysis is performed, and the structural behaviour of the base isolation device is suitably investigated. The analysis is intended so that the base isolation device can suitably perform under events characterized by high values of peak ground acceleration and events with high energetic content. The analysis is performed of the different phases of the mathematical behaviour of the base isolation device and the mathematical simulation of the base isolation device is properly illustrated.
