ABSTRACT:
A structural strut having at least one surface of generally U-shaped cross section and being formed with a pair of upstanding side walls having opposed tapers. The side wall tapers of the strut shift or skew the neutral axis of the member in proportion to the relative side wall dimensions. In this manner, the strut may be used to comprise a load bearing member having a neutral axis selectively slanted to a position maximizing structural loading efficiency and interconnection. The ends of the strut are further formed of substantially planar construction for flat abutment and welded attachment to cross members of a truss thereby eliminating conventional gusset plates. The structural strut may also be constructed from a pair of such U-shaped channel sections secured back-to-back with the tapering flanges complementally positioned opposite one another for selectively shifting the neutral axis of the resulting I-beam. In this manner, the strut beams of the invention present their respective neutral axes in the most advantageous configuration for maximum structural integrity and efficient interconnection.
