Torsion Constant - Stiffeners
Torsion Constant - Stiffeners
(OP)
Hi! From what I know torsion constant value is highest when the section is a closed shape. But what if the section is not enough to accommodate applied loads? Could we put stiffeners to increase the shape's torsional stiffness ? Just like in the picture (plan view of an aluminum tube-green). Could we consider the snap on cover (high-lighted in red) to be like a solid part of the section? Or will the steel channel (yellow) help with the torsion constant?
Thank you in advance for your ideas.

I would also suggest that when you reinforce aluminum extrusions with steel sections, that you isolate the two by a heavy paint coating on the steel to mitigate potential corrosion issues of the dissimilar materials being in contact.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
