HSS to HSS Connection
HSS to HSS Connection
(OP)
Can someone help me with the design of a welded connection for a short stub beam to the main beam. This will be a moment connection since the short stub beam ( about 12" long) will support an equipment
hanger load. The main beam HSS 14 x 6 x[indent][/indent] 1/2" has been sized for torsion created by the cantilevered load. The tentative size of the stub beam is HSS 8 x 4 x 1/2". I would like to weld the two members in the field without connection angles.
Thank you for any help or direction you can provide.

RE: HSS to HSS Connection
I recommend using Blodgett ‘Design of Welded Structures’ method of checking the weld group as a line if there are lateral loads & thus biaxial moments on the weld.
If only vertical loads on the HSS (no seismic), you could just resolve the moment into a force couple and check the top & bottom welds alone.

1) Deliver your shear in short weld segments near the centroid of the cantilevered member.
2) Split your monent up into a couple of line loads at the flanges.
3) Flexurally design a vertical strip of girder HSS wall for the line loads just described assuming the strip to be pin ended.
That should take you 10 min and will work for modest loads. If it doesn't work, move on to something more sophisticated.
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.

Rectangular to rectangular connections as well as round tubes to round tubes.
