Abstract
The disclosed seismic isolation bearing includes an upper base plate, a lower base plate, a disc bearing core, and a shear spring surrounding the disc bearing core. Concave recesses are formed in a lower surface of the upper base plate and an upper surface of the lower base plate. The disc bearing core is centrally positioned with respect to the planes of the upper and lower base plates and can slide along the recesses of the upper and lower base plates, where the recesses exert a lateral return force on the disc bearing core when displaced from a central position. The shear spring surrounds the disc bearing core, deforms in shear upon lateral movement of the upper base plate relative to the lower base plate, and exerts a lateral return force on the upper base plate when the upper base plate is laterally displaced.
