Abstract
A channel-shaped section has a thin, local reinforcement shell separated from the channel-shaped section by a layer of structural foam. At the reinforced section an arch geometry is utilized which extends in a direction opposite that of the force to which the member is subjected. The arch may be present as the channel-shaped member, the reinforcement shell or both the channel-shaped member and the shell. A portion of the shell contacts the channel-shaped member and is attached thereto by welding or other means of attachment.
