Circular Ties in Concrete Pile
Circular Ties in Concrete Pile
(OP)
In pile design, 10M (approx #3) @12” ties are usually specified (from what I know) regardless of pile diameter, etc. I wonder if this is always good from you experience? And the ties are cut with certain overlap (e.g. 16”) only, no hooks! This has bugged me for a while. From the function of transverse rebar, the hook is definitely required in column, but for piles because of the soil restraint …… What do you think?






RE: Circular Ties in Concrete Pile
CRSI has a recommended Class A lap for circular ties in columns - which, for a #3 bar in f'c = 4000 psi concrete is 14".
Weird, but in the same CRSI manual, for drilled piers, they call out a lap of 48 x db which is 18" (Class B lap) for a #3 tie.
