Self-centring and energy-dissipating seismic isolation device and system of the elastomeric-frictional type
A self-centring and energy dissipating seismic isolation device of the elastomeric frictional-type for structures and industrial equipment comprises: first and second metal plates respectively joined, one to the structure or equipment and the other to its foundations, the first metal plate being fixed thereto and the second metal plate being rotatably joined thereto by a column; at least one elastomeric ring between the plates; and a central restrictive bar orthogonally joined to the first plate and extending through the elastomeric ring and through a central through-hole in the second plate, a nut being screwed to the free end of the bar and having a spherical curved-convex bottom in sliding contact and corresponding with a spherical curved-concave inner surface part of the central through-hole. An isolation system can comprise several of these devices and columns or just one pair of devices at the ends of a central column in combination with sliding support pillars.
