HSS Beam Moment Frame
HSS Beam Moment Frame
(OP)
I am retrofitting an existing facility and I am attempting to remove two adjacent building endwalls and combine them into one. Geometry dimensional restrictions abound so I am left with using an HSS beam to carry the torsion of unbalanced flange loading to the frame columns. The frame takes building lateral load as well. My question is related to the welding of the HSS beam to an extended end plate. The weld of the upper flange to end plate is required to transmit all tensile forces resulting from the moment, correct? Welds along the side should not contribute to the tensile resistance correct?My plan was to require a fillet weld around the perimeter of the HSS beam, but preliminary sizes indicate that a CJ weld may be required. See attached sketch.

I agree with BA that this is most likely the case in the real world.

That rational may not apply as directly to HSS moment connetions. Especially if this is not a seismic application where you expect to get significant non-linear behavior in your moment connection.
