Hardworker87, thank you. This paper is also part of my study. It has great information on pullout strength of L-bolts. J-bolts with concrete failure still eludes me.
Does ETAG consider the presence of the grout or just the fact that there is an offset? ACI accounts for the fact that grout adds to the shear resistance. Grout and steel have coefficient of friction of 0.40. I believe the 0.80 accounts for the fact that there is some reduction in the shear...
I am evaluating hooked bolts used to anchor equipment like pumps and tanks in nuclear facilities. Hooked bolts were popular in the first and second generation power plants. I did hear about the failure of the metal frame building, very interesting article. I am familiar with the Breen paper...
Im particularly interested in J-bolts in concrete which can fail in either pullout, steel, splitting, or concrete breakout. The code concrete breakout equations from ACI 318 were developed from undercut and headed bolt tests and were applied to J and L bolts. I have not found a single test...

I have combed the internet for J-bolts test and have not found anything related to smooth J-bolts similar to those used for foundation bolts.
