Top of Anchor Bolt Embedment Depth

Top of Anchor Bolt Embedment Depth

(OP)
So, here is the deal. We are designing a building with precast hollow-core planks on the 2nd floor, supported by precast beams and columns. On top of the concrete columns are steel columns. There is a 4" concrete topping to be poured over the top of the hollow cores and the baseplate on the steel column. Is there a minimum cover depth from the top of the concrete topping to the top of the anchor bolt or to the top of the nut? I have been searching for anything, but I'm coming up empty.

RE: Top of Anchor Bolt Embedment Depth

No requirement I know. Some engineers may use the cover requirements for reinforcing. Since the cover is non-structural, this would be more important if the topping slab is exposed to weather. If not exposed to weather, I would specify 1/2" min (similar to shear studs for composite decks in AISC 360).
