  • Seismic energy damping system
    Patent number: 7743563
    Abstract: A seismic energy damping system with plural redundancy for a building or structure subject to seismic perturbation (i.e., deflection of the building structure) includes a distributed plurality of seismic energy dampers, and a plurality of rigid shear panels cooperating with the building structure via the seismic energy dampers. The plural shear panels and plural seismic energy dampers distribute seismic energy absorption and dissipation throughout the building structure to avoid stress concentrations, and to dissipate significant seismic energy, thus limiting the amplitude of deflections of the building structure during a seismic event.
    Type: Grant

  • Seismic energy damping apparatus
    Patent number: 7584578
    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.
