End plate check for shear yielding

[BAGW]

HI,

I have q question regarding the end plate design per DG 4 section 3.12. Is this check more for tension component of the flange forces? Code is not clear regarding this. Thanks

The entire theory behind DG 4, DG 16 and upcoming DG with more connections is that you only design the tension side of a bolted endplate. The compression side of the moment connection transfers it's force through bearing. You'll want to check but it's generally assumed that the bolts on the compression side carry the shear. I don't know if DG 4 verbalizes that but DG 16 does (I believe).

I second Sandwich's response. As long as the compression flange force is being transmitted to an adjacent column stiffener via direct bearing, there is, ostensibly, no shear in the end plate on that side of the joint. Or, at the least, there doesn't need to be any shear resistance there.
