This paper describes a preliminary experimental study aimed at investigating the force-displacement behavior of Variable Friction base isolation Systems (VFSs). Full-scale VFS prototypes were tested under cyclic loading conditions. A series of dynamic hybrid tests simulating the response of a full-scale single-story structure isolated with VFS devices and subjected to ground motions with different intensities, was also performed. The results of the experiments are presented and used to provide some preliminary validation of a previously developed numerical model. Overall, the results of the experiments were in good agreement with the predictions provided by the numerical analyses.
