Hilti Profis Problem?
Hilti Profis Problem?
(OP)
I am using Hilti Profis Anchor 2.4.9 with ACI 318-11 strength design. I think that Profis may be incorrectly limiting concrete breakout capacity of cast-in-place anchors. For ACI 318-11 design, Profis limits the embedment to 25” regardless of the thickness of the member. However, according to the ACI 318-11, this limitation does not exist anymore - I guess because test data *is* available. I have upgraded Profis to the latest version, but no change.
Quote (PCI Journal Winter 2013)
ACI 318-08 also imposed a 25 in. (635 mm) limitation on the anchor embedment depth for the calculation of concrete breakout strength using the provisions of appendix D. This limitation was effectively removed by section 1908.1.10 of the 2009 IBC. ACI 318-11 does not have this limitation anymore.

It may not really be an error by Profis, but a limitation they chose to keep so people don't go crazy with embeddment depths.
