US Patent 7743563 Seismic energy damping system

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.
