Pullout strength formula [D-15/ACI318-11]
(OP)
Does anyone know from where this equation comes Np=8*Abrg*f'c, i cant understand the multiplier 8 in the equation, it is not consequent with the bearing strength calculations of 0,85f'c. If anybody knows, Thanks.

"The following section establishes limitations for the combined
effects of bolt spacing, embedment depth and edge
distance, such that the heavy hex head on a standard anchor
bolt provides "full anchorage" in concrete equal to the
tensile capacity of the bolt. Several agencies/authors have
published reports representing their test data and/or recommendations
to account for these variables, (see Refs. 9,
10, 13, 16 and 17)."
I assume the next step would be to go hunt up those references.
