ABSTRACT:
An isolation bearing for structures includes interlocking channels arranged in pairs of rows in which adjoining pairs of rows can be aligned or staggered. A transverse anchor rod controls the deformation of the side walls of the channels. Kinetic energy is absorbed in the bearing by deformation of the elastomer, deformation of the metal components, and by friction. Elastomer bulge is controlled by plates at the ends of the channels. Stress distribution in the walls of the channels is controlled by oppositely slanted slots. The channels are made from metal tubing or I-beams.
