ABSTRACT:
An energy absorbing load carrying strut is provided by laterally restraining a malleable column against eccentric loading bending moments. Lateral restraint is provided by a sleeve extending around the column and, in some embodiments, a rod extending through the column. The sleeve and rod extend over the full length of the column and are so secured as to laterally restrain the column against buckling and not be subject to substantial axial loading as the result of axial loading of the column. The restraint thus provided enables the column to maintain its load carrying capacity while being loaded beyond its yield point.
