Why can’t I select the option to use an oversize plate or washer equal to 1.0?
Dear customer,
Thank you for reaching out to us. The option to use an oversize plate or washer is only available in PROFIS Anchor for cast-in-place headed bolts (ASTM F1554 hex head, heavy hex head, square head and heavy square head) when design per ACI 318-11 or ACI 318-14 is selected. This option is not available in PROFIS Anchor for either AWS D1.1 headed studs or for Hilti post-installed anchors; nor is it available if design per ACI 318-08 or ACI 349-01 is selected.
Reference ACI 318-11 Part D.5.2.8 or ACI 318-14 Section 17.4.2.8 for the design provisions relevant to use of an oversized plate or washer.
I hope I have answered your question. If there is anything else, please let me know.
Cheers
Morgan
