50% of this thickness = 37.5 inches and the source of the discrepancy. Generally speaking, the post-installed end of reinforcing bar must be straight because only a straight section can be inserted into a drilled hole that is filled. ACI 318 defines a post-installed anchor as an anchor installed in hardened concrete. Your baseplate thickness is set to 75 inches. PROFIS Rebar calculations are only relevant to calculating straight bar development lengths. I'm going to actually email Powers about this as I don't think there should be such a drastic difference between the two.Įdit: See above, dylansdad has the answer. Overall I'd say it's an error (or there's something hidden in the black box we are missing). Otherwise it appears they should be calculating L b the same and getting roughly similar numbers for the capacity. The anchor design methods in PROFIS Anchor require rigid anchor plates per current regulations (ETAG 001/Annex C, EOTA TR029, etc.). Looking in the help file, Powers appears to add in the baseplate (fixure) thickness which Hilti does not from what I can tell. That said, it appears to be roughly the same calculations. The PROFIS Engineering Suite makes tackling even the most complex and challenging anchoring projects easier. As Powers PDA is programmed for both European and US usage I would guess they default to the more conservative check. Powers designs the lever arm per ETAG 001 Annex C.
