RE: Reference for screwed connections in structural steel

Check out the NASA 1228
It will not have the official blessing of the IFI, AISC or the RCSC, but it provides an engineering solution.

Look at the December issue of MSC magazine on page 9.  The topic is "Strength of a Tapped Hole".   We had this situation happened earlier this year and it became a problem of installing and tensioning a Gr 5 bolt into a less than A36 plate with limited thread length.

Seems similar to traditional type build-up of sections using rivets before welding available. Screws typically used with cold-formed steel, so resistances can be checked against cold-formed steel code.
