If this additional contribution
is to be utilised, the transverse
stiffeners should be full depth and
approximately the same width and
thickness as the column flanges. The
welds between the stiffeners and
the flanges should be full strength,
because the full plastic moment
resistance of the stiffeners is assumed
in the calculation.
