Abstract
The present invention relates to apparatus and systems for absorbing seismic energy to prevent non-linear displacement in a structure. A seismic damper according to embodiments of the present invention includes a flat plate which can be perforated to include a plurality of apertures and/or cut-outs. A central aperture is formed in the flat plate and one or more cut-outs are formed along outer edges of the flat plate. The area of the flat plate between the aperture and the cut-outs forms one or more nodes on which stresses from seismic activity are focused, and which can deform to absorb energy, thereby reducing or preventing non-linear displacement of a brace system to which the seismic damper is attached. The nodes are located at the intersection between one or more tabs, the tabs being arranged to be connected to braces within the brace system.
