Figure 2.11
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.
