Abstract
An energy absorbing assembly in which a number of spaced, metallic plate-like elements are coupled together by end blocks and spacers clamped together so that the elements are generally parallel with each other and are cantilevered from the upper ends thereof. In one embodiment, the upper ends of the elements are rigidly coupled to a floor beam and the cantilevered ends are coupled by a plate-like strut to an adjacent column to which the floor beam is pivotally mounted. A number of rollers permit free movement of the lower ends of the plates relative to the upper ends thereof. In a second embodiment, the assembly has elements which are bow tie-shaped plates, and the upper ends of the elements are rigidly secured to a horizontal floor beam. Diagonal braces are secured at opposed lower ends of the elements, and the lower ends of the braces extend downwardly and away from each other and are secured to the next floor beam therebelow.
