Highly Effective Seismic Energy Dissipation Apparatus
view source
US Patent:

20010045069, Nov 29, 2001
Filed:

Mar 28, 2001
Appl. No.:

09/819191
Inventors:

Michael Constantinou - Amherst NY, US
Assignee:

The Research Foundation of the State University of New York at Buffalo - Amherst NY
International Classification:

E04H009/02
US Classification:

052/167300, 052/167400, 248/636000, 248/638000, 188/280000
Abstract:

An energy dissipation apparatus for installation in structural frames to mitigate seismic effects comprises a scissor-jack system of braces with an energy dissipation device such as a viscous, viscoelastic, or hysteretic damper, or an active or semi-active device, connected between opposing pivot joints of the scissor-scissor jack system. The scissor jack system magnifies displacement so that energy is dissipated more effectively by the damper. Open bay, diagonal, and alternative installation arrangements with respect a structural frame are disclosed.

US Patent:

20130118098, May 16, 2013
Filed:

Nov 9, 2012
Appl. No.:

13/673257
Inventors:

Michael C. Constantinou - Amherst NY, US
Andrei M. Reinhorn - Williamsville NY, US
Apostolos A. Sarlis - Buffalo NY, US
Douglas Taylor - N. Tonawanda NY, US
David A. Lee - Santa Monica CA, US
Satish Nagarajaiah - Sugar Land TX, US
Dharma Theja R. Pasala - Houston TX, US
International Classification:

E04H 9/02
E04B 1/98
US Classification:

521671, 527413
Abstract:

A negative stiffness device and method for seismic protection of a structure is described. In one embodiment, the device has an anchor frame and a movement frame laterally translatable relative to the anchor frame. The anchor frame and movement frame have respective extension portions. A linkage is pivotably connected to the extension portion of the anchor frame. A compressed spring has a first end is attached to the extension portion of the movement frame and a second end attached to the linkage. The compressed spring has a spring force. In a rest state, the compressed spring does not apply a lateral force to the movement frame. In an engaged state, the compressed spring is configured to apply a lateral force to displace the movement frame in a lateral direction of a seismic load. The spring force is amplified by the linkage when the movement frame is laterally displaced to an amplification point.
