Minimum embedment of a steel pipe into a concrete cap?
Minimum embedment of a steel pipe into a concrete cap?
(OP)
The CRSI Design Handbook indicates a minimum 6 inch embedment for steel piles into concrete caps, stating that it is a good practice for structural steel shapes to avoid use of cover plates for bearing.
Why would embedment affect the bearing capacity at the interface between the top of the pile and the cap? It seems to me like it would all be based on contact area. Why would the embedment matter? I know a certain amount is required for lateral stability.

Is the embedment contribution quantified somewhere? What if I can prove that the top of the pile meets ACI's bearing provisions?
I thought natural friction bond between concrete and steel was minimal without an applied normal force. How would you calculate the contribution from the friction interface?

I would not rely on friction between steel and concrete. I can't see anything wrong with using a cap plate if you need more bearing area.
