Abstract: Axial buckling restrained braces are provided. In various embodiments, a device comprises a plurality of cylindrical sleeves arranged parallel to each other. Each of the plurality of sleeves has an interior surface defining an interior region. A plastically deformable rod is arranged within the interior region of each of the plurality of sleeves. The plastically deformable rod is adapted to assume a helical shape upon compression.
Abstract: A seismic axial dampener device is constructed of a multitude of composite or metallic conical compression discs and an exo-structure capable of dampening both tension and compression cycles of a building structure due to a seismic, explosion, or wind event. The dampener reacts and dampens the loading in both tension and compression along the axis of the cross brace in linear-elastic bending, creating internal hoop stress, and not through shear of the dampener device.
