Say you have an HSS 8x8 column and you want to frame a horizontal beam (another tube section) into the side of it. We also want the beam to extend past the column and cantilever out a bit.
At first I thought I'd just use a bit smaller sized beam - say an HSS6x6 and just fillet weld around the ends on the faces of the HSS8x8 - but I got to worrying about distortion in the face of the column when moment is applied at the connection from gravity loads on the beams. I have the AISC Hollow Structural Sections - Connection Manual - but it only has HSS to WF connections - not tube to tube (which is kinda strange).
I know that using a single vertical plate shear connection on the face of tube columns has been found to be OK (i.e. no serious distortions. Would this moment connection idea be OK as well? - as long as the beam wasn't too much smaller than the column width? What do you think?
