Castellated beam elevation
According to the manufacturer, castellated beams are manufactured by cutting a wide flange along the web in a "zig-zag" pattern, offsetting the two halves, and welding the two halves together, as shown in the next figure. As a result, the underlying steel section is a wide flange (W shapes) in the AISC table or a B shape. STAAD currently supports only the ones derived from W shapes.
