Seismic isolators

These isolators are the combination of a bearing and dampers in a single device; the latter are typically hysteretic dampers of steel and/or fluid viscous dampers. As such, they are characterized by a high damping capacity. The bearing can be multidirectional or unidirectional. Isolators can also include shock transmitters or mechanical fuse restraints.
