Pullout Capacity of Pipe Piles in a Concrete Cap
Pullout Capacity of Pipe Piles in a Concrete Cap
(OP)
Has anyone seen work on the bond strength of a steel pipe pile into a concrete pile cap? For significant uplift you would want nelson studs or rebar to develop the strength of the pile, but that's a lot of labour if you're just looking at a nominal load. There's obviously some frictional or bond strength between the concrete and the steel, but I don't know how to quantify it. A brief search of the internet and my literature doesn't seem to come up with anything directly applicable.

I stood under a pile hammer counting blows for about 400 pipe piling at a grain terminal project on the Mississippi River many years ago and remember being covered in oil/grease at the end of the day.
Perhaps today's hammers are cleaner but I'd still wonder.

Might want to 180 hook the Ls if you're tight packed and deep capped.
