Patent abstract
A seismic energy damper includes a pair of structure members subject to relative motion during a seismic event, and a pair of friction washers each fixed to a respective one of the structure members and moving relative to one another during the seismic event. A tie bolt resiliently urges the pair of friction washers toward frictional cooperation, and a friction member cooperates with the pair of friction washers to dissipate seismic energy.
