Not really but thank you. So far I have been looking at the bending of the web which isn't giving me enough so I have added a stiffener just under the slotted hole in the web for the diagonal brace. This is such a "popular" type of connection that I am surprised that there isn't more info on an established design procedure for it.

I bit the bullet and made a risa fem plate model. I did use the YLT to design the top of a concrete vault years ago and I recall being amazed at how simple and efficient the method is. It really felt like engineering magic. I'll have to check this model with it. Thanks BA. I wasn't able to load an image, but I was able to create a slotted hole, and yes it did need a doubler plate. I experimented with plates perpendicular to the web, but the doubler had the most effect in reducing the stress around the hole.
I'm still surprised there isn't a table with published values for this situation.

Why don’t you ‘bit the bullet’ again, you already ‘made a risa fem plate model’ and build us all that ‘ table with published values for this situation.’ Everything in this world doesn’t come for nothing or a quick Google. Maybe a nomograph would be a better presentation for such a problem. Maybe some of the variables would be load and its angle, double pl. thickness vs. col. web thk., double pl. width to height a/b. You could also show some yield line solutions to the problem and how they compare with the FEA solutions. Then provide a welding design btwn. the column and the doubler pl.
