Anchorage design for large diameter anchor bolts
Anchorage design for large diameter anchor bolts
(OP)
I am designing the anchorage of some large pylons with very large moments (approx. 65,000 k-ft unfactored). They will be anchored into large mat foundations with an annular anchor bolt pattern utilizing (34) 3.5" diameter anchor bolts on a 144" bolt circle.
Checking the anchor bolt steel strength is not too difficult, however, the concrete anchorage has me a little stumped. ACI 318 app. D does not seem to apply per D4.2.2. Does anyone know of an ACI code that would govern this application. Thanks.

Note that if the dowels are participating (by mechanical requirement, not just installation) in compressive force to be transmitted to the mat, their individual compression needs to be effectively transmitted to the same by whatever device.
