Rectangular HSS Beam-- Fixed Support
Rectangular HSS Beam-- Fixed Support
(OP)
I have a 14 x 4 x 3/8 HSS beam that carries torsion to the end supports and I have been unable to find an example for the design. I am thinking of a stiffener plate on each side of the
section welded to the bearing plate and face of the tube with the overturning forces (couple) taken into the anchor bolts and into the concrete support. The other thought is to use holdown
clip angles, the same idea as used in building columns. I am wondering if someone out there has been there done that or can direct me to an example. I can't find anything in my textbooks.
Thank you for any help you can give me.

there are of course other ways (to skin this cat) but your's sounds ok to me.

Is this an HSS tying into a concrete wall? Side of wall? End of wall?
Big or small moments/torques?
Does the wall exist or is it part of the new construction?
Can tolerances be accommodated at the other end of the beam or do they need to be accommodated at this connection?
How sensitive will your structure be to twisting of the HSS?
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.

Before I try to wing it I was asking if anyone has a design example of this analysis/design. I have searched my text books and AISC to no avail.
Thanks for any help you can provide.

1) split your torsion up into a top and bottom face force couple. Size welds and apply them all around for good measure.
2) apply the top face load determined above to the top of the end plate as a load in a cantilevered plate and design through to the concrete accordingly.

find anything closer to my situation. Back then he had nothing covering HSS sections.
Thanks
