How many others out there have serious doubts about the validity of ACI’s anchorage system (Appendix D)? I think that much of it is based on research and good theories, but there are parts that appear so far out of any intuitive common sense that I find myself continually questioning results, either by hand calcs or by something like Hilti Profis. Most common are the “concrete edge break-out” results which seem to always control the designs - despite adding huge edge distances to a problem.
With this lack of intuitive rationality in App. D results, I find myself wanting to blow it off as inaccurate and sometimes “go my own way” with an anchorage scheme that Profis tells me is failing.
Anyone else suffer from “App D sucks syndrome”?
