Abstract
A high strength and low mass hard bar bumper assembly which has an interior bulk head to maximize beam face support for minimizing face dishing which maintains beam section shape by tying the flanges together and which transfers the impact loads from the beam face to the beam flanges. In the preferred embodiment, a hollow cylinder is used as the tie bolt and a resilient opened-celled bulkhead spacer is used to transfer loads from the face through the hollow tie bolt to the flanges.
