HSS Localized Yielding from Shear Plate
HSS Localized Yielding from Shear Plate
(OP)
I am designing an HSS column which has a vertical plate with a shear load welded to the column wall. Looking in AISC 14th edition, Table K1.2 on page 16.1-144, it says that the limits are for the plate (which is all set) and the HSS punching shear, which gives the formula in the table. However, this formula is not dependent on the plate's shear load.
My question is shouldn't the thickness of the column wall be dependent on the shear load, since it would be localized? It does say to see Chapter J to calculate Rn, but frustratingly doesn't specify where. Can anyone point to the correct formula, if one exists, to calculate the shear load limit dependent on the HSS column wall thickness?

It says to calculate Rn, see Chapter J. So what I was unsure of is did they mean for the limit of the plates, welds, column or all three? I know how to check the welds and the plate for its limits, its the HSS I'm not sure of, maybe it doesn't need a check other than punching shear, I'm just surprised that it doesn't take the load moving from the weld to the edge of the column into consideration (I have a 74.2k load using a 3/8" shear plate into an HSS 6x6x1/4). I just find it odd there isn't some check for the column wall deforming under such a load.
