I apologize if this has been asked before but I could not find anything in the archives. The PCA Notes on ACI 318 mention several times that anchor pryout is really only a concern on short stiff anchors. I was wondering if an actual limit where anchor pryout does not need to be considered is specified anywhere in the code? I know that the document "Design of Anchor Reinforcement in Concrete Pedestals" which is linked to in other posts mentions a limit of hef,min = 12 on Page 5. Although I would agree with this limit it appears to be a judgement call and not referenced by any code. Your thoughts? At what point, if any, are you guys ignoring the pryout on anchors?
Although I am asking this question in general the specific case I am working on has (6) - 1-1/2" diameter anchor rods with a 24" embedment and a 15" edge distance. After using supplemental reinforcing for tension and shear, pryout would be my controlling condition.
