W Shapes to HSS Columns
W Shapes to HSS Columns
(OP)
I'm looking for a guide to designing connections (shear and shear/axial) connections to HSS columns.
The Canadian guides are very simplistic, basically checking punching shear for a shear tab, and that is all.
Does anyone have any suggestions?

Also when you have a large shear force in a beam into the side of a HSS column, how does that force entering in wall distribute to the entire HSS section?

Check AISC publication on design of HSS connections.
RE: W Shapes to HSS Columns
If you have a slender wall you probably should use a through plate connection.
pg. 1-93 has a handy chart for compactness criteria.

Then you add a braced bay to that, and I have a large amount of forces to be connected taht need to pass through the HSS. I do use through plates sometimes, but sometimes I wonder if it's really necessary or not.
My rule of thumb so far has been if the column is "slender" to reinforce with a plate behind the shear plate if just shear, and to use a thru plate if there is axial load in the beam.
I was wondering if anyone else had a reference guide or text they used to further refine the design.
Thanks for the replies so far

Beyond that, I would use a knife plate welded to the center line of the HSS with a horizontal stiffener top and bottom.

Tests have shown that there is no advantage to using through plates as opposed to shear tabs if the column is Class 3 or better. For thin-walled HSS, through plates may be necessary.
