Title:
ENERGY ABSORBER
Document Type and Number:
WIPO Patent Application WO1999002887
Kind Code:
A3
Abstract:
The invention described is an energy absorbing bearing with a primary application in the seismic isolation of a structure from the ground or parts of other structures. It may also be used to dampen other forces on structures on which it is installed. The bearing consists of end plates (12, 14) separated by a laminate of resilient (16) and stiffening layers (19). In a preferred embodiment there is a plastically deformable insert (22) within the laminate. The laminate interfaces with the end plates in each bearing are secured near the central axis from end plate to end plate, but not near the peripheries. The advantage provided is allowing a wider range of forces to be absorbed than with known bearings of this type. Also described are novel laminae and novel means for securing the laminae and end plates.
