  • Seismic isolation system between floor and foundation comprising a ball and socket joint and elastic or elastomeric element
    Patent number: 6324795
    Abstract: A seismic isolation system with a plurality of ball-and-socket joints attaching a base structure to a plurality of foundation pads or piers. A plurality of pads or piers 3, 13 form a foundation structure. A seismic isolation bearing 20 attaches a pad to the floor 1 of a building or other structure. The seismic isolation bearing includes a joint 22 attached to an elastic element 12. The seismic isolation bearing allows tilting of the pad in relation to the base structure in response to vertical movement of a foundation pad. Additionally, rotation of the joint works in conjunction with the elastic element to reduce the shear deformation in the elastic element in response to transverse movement of the foundation pad.
