Seismic Energy Damping System
US Patent:
7743563, Jun 29, 2010
Filed:
Oct 21, 2006
Appl. No.:
11/585062
Inventors:
Said I. Hilmy - Irvine CA, US
International Classification:
E04B 1/98, E04H 9/02
US Classification:
521671, 521678, 521673, 521674, 521672, 521679
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.
Seismic Energy Damping Apparatus
US Patent:
2008009, Apr 24, 2008
Filed:
Oct 21, 2006
Appl. No.:
11/585063
Inventors:
Said I. Hilmy - Irvine CA, US
International Classification:
E04H 9/02
US Classification:
521678
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.
