A foldably constructed force-resisting structure comprises a top member and a bottom member foldably constructed and assembled from one or more blanks of sheet material, preferably corrugated paperboard, initially in a flat condition. The top member includes a base panel and at least one side portion folded downwardly from the base panel. The bottom member includes a base panel and at least one side portion folded upwardly from the base panel. The top and bottom members are assembled in nested relation to define an interior of the force-resisting structure between the base panels, which are at least substantially parallel to one another. The force-resisting structure includes a vertical support rib structure in the interior defining an X-shaped or cross-shaped configuration. The support rib structure is foldably constructed from the top member base panel and/or the bottom member base panel and provides vertical support for a load disposed on the base panel of the top member.
