ABSTRACT:
An arcuate or circular profile element of generally V-shaped cross-section has a curved bottom wall, arcuate sidewalls having free edges, and laterally projecting flanges projecting from the free edges. By choosing specific relationships between the thickness of the different parts of the element, lighter-weight elements can be used to withstand the same loads as before, or elements having the same weight as before can be used to support heavier loads.
