Curved WT Beam
Curved WT Beam
(OP)
i have an architect who would like a curved WT9x38 beam, with the flange on the outer most radius of the curve. The radius is about 5'4" and makes a half a circle.
i'm worried whether this is possible with the WT beam. i see the web buckling during bending but what do i know. could make this with plates but they'd like the radius.

In summary:
1) Use their recommended tool to figure out what might be possible with a W-shape rolled the hard way.
2) Assume, at worst, that your WT might be rolled as a W before being cut into a T.
3) Per jayrod, hokie, and the article, call a fabricator to confirm.
Or just skip to #3. Your call.

I specified WT rolled the easy way for a curvy truss chord one time. No push back.

You might have better luck with a 12" channel with the toes in, or with a 12"x4" HSS. Depending upon how it is loaded and what it actually does, I would fabricate it with a 12" x .5" flange and a .5" thk. stem. I might allow that the stem be cut in two 90̊ sectors and welded back together to make up the full half circle.

cpiedra23 - Can the architect handle some welding being present? You could get this entire thing cut out of one PL0.75" 5'x10' and weld it all up AND have enough drop left over to make a bomb-proof mailbox!. Just a thought.

I'd try it at home.
