Cantilevered Tube
Cantilevered Tube
(OP)
Hi,
I have a 10x6 tube welded to a column to support a concrete panel. Its cantilevered 3'-0" off the column, to support a 13K load. By design I can get the tube, weld, deflection to work. Is there any worry of the tube rolling, and buckling? I cant convince myself that the tube is ok.
Any input would be great

RE: Cantilevered Tube
This would induce a torsion of 13K x 3" = 39kip-inch. (I am assuming the 6" tube face is horizontal and the 10" face is vertical). On the face of it, this doesn't seem to be a very large torsion load to a tube member.
Resolve your forces and check. Keep in mind that the column must also be able to resist this torsion load as well.
Off the top of my head, I would think you could get a 10x6 tube to work without too much a problem. May require bumping up the wall a size or two, but not a big issue.
RE: Cantilevered Tube
I would expect it would only effect the welds/bolts which will have more shear load from the torsion.
Have you done a full analysis of the connection to the HSS connections Manual?
