Abstract
The influence of the main mechanical parameter choices on the response of fluid viscous devices used in base isolation applications, is analyzed. Whereas the stiffness characteristics of these systems can be easily fixed to achieve the desired decoupling effects between foundation and superstructure motions, much care is required to suitably define their damping properties. Attention is therefore focused on this aspect, by examining a series of spectral response curves obtained from real and artificial input accelerograms for selected ranges of damping governing parameter.
