J bolts
(OP)
I have been asked to use J bolts for anchor design. Are there any design aids or examples out there? I've done my web searches and there is not much out there on J bolt design. The client specified the material, diameter, and 90 deg hook length (which happens to be 6db vs the normal 12db). Not sure how to reduce the capacity due to the shorter hook length? Does anyone have any references they could point me to?

I would recommend against hooked bolts though. AISC recommends against them in any situation where tension is applied.

DG #1 also used to have minimum embedments (usually some number of diameters), but App. D doesn't recognize a minimum, just whatever it needs to be to work. That being said, we use a minimum of 9" for a 3/4" anchor rod. If I end up with a bigger anchor then it typically needs a much deeper embedment anyway.
