Metodo di progetto di dispositivi siliconici per l’isolamento alla base: applicazione a due casi sperimentali

The main aspects of the design of the silicone-fluid devices to be incorporated in the base isolation system of two full-scale frames, which will be tested at the ELSA Laboratory (Ispra), are illustrated in this paper. The analysis is developed by a general design procedure consisting in a preliminary design phase of the spring-damper elements, and a final verification aimed at assessing the correlation between the obtained response and the required performance. Preliminarily to the future test campaign, the numerical enquiry carried out for the two frames shows the procedure convergence, and validates relevant design parameter choices.
