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.
