Abstract
A guardrail support post includes a continuous structural member having a top edge, a bottom edge, and a generally uniform cross section from the top edge to the bottom edge. The structural member includes first and second generally parallel flanges, and a web forming a coupling between, and extending generally perpendicular to the first and second flanges. The structural member includes a lower portion for installing below grade adjacent a roadway, and an upper portion configured to be coupled with a guardrail beam. A mid portion of the structural member is disposed between the upper portion and the lower portion. In accordance with a particular embodiment of the present invention, the first and second flanges include first and second cutouts, respectively, that occur within the mid portion. The cutouts are operable to weaken the structural member about an axis generally perpendicular to the flanges without substantially weakening the structural member about an axis generally parallel to the flanges.
