Title: RE: UBC 1630. Bracing Load
Check out the AISC Journal from about 25 years ago. There was research done on A307 SP connections with formulas. The design usually required slotted holes. I used to use it all the time. I still have spread sheets that include A307's for these connections. As far as I know, nothing prohibits their use other than lack of a readily available design procedure. AISC abandoned the procedure probably because A307 bolts are not fashionable enough.<g>

What do I use (table or procedure) if I want to use A-307 bolts in a single plate connection?
