Abstract
A pole reinforcement truss has an open cross-sectional configuration characterized by opposite side flanges that diverge with respect to one another as they extend from respective opposite side edges of the truss body. In a preferred cross-sectional configuration, five curved bends of equal obtuse angle and radius of curvature are used to define the side flanges, a pair of bridge portions, and a pair of apex portions in symmetrical arrangement. The truss maintains its geometry in an improved manner after the onset of yielding, thereby increasing ultimate strength of the pole-truss assembly.
