Answer:
Matthew,
I assume we are talking about a flange that belongs to an I-beam, or a
wide-flange beam.
Probably you have one flange well-supported, but the other one can
buckle.
There are several possible modes depending on proportions and
constraints.
One practical way is to build a little FEA model and run buckling.
There are at least two different ways I can think of to stiffen the
flange.
One would be to make a set of triangles, one side of the same length
as the width half-flange.
Then weld those in to connect web and flange alternating web sides as you
go along.
Keep the distance between the succesive triangles close to the
width half-flange.
The other way is to cut two long strips and attach them to the tip of
flange,
on both sides of the web, at right angles to the flange. Height of each
strip
should be half the width of half-flange.
Hope this helps a little.
