Concrete Pile Caps to Steel Piles

Concrete Pile Caps to Steel Piles

Concrete Pile Caps to Steel Piles

(OP)
Can anybody point me to some literature on the design of concrete piles caps to steel piles?  Anything available on the web?  I have some steel driven piles installed for a gas bar canopy (substituted for a franki / compacto piles)and asked for the contractor to have the pile installer verify that the steel piles can take the canopy moment loads.  They have come back and stated that they have to encase the top of the pile with 1200 high x some diameter with concrete to ensure that the pile can take the moment load?  I never heard of this before.  This leads me to looking for more info on concrete pile caps to steel piles and the design of concrete to steel relationship and load transfer.  

If there is no readily available literature I would appreciate some prompt guidance on what to do.  I can provide more data as required.

Thanks in advance for your advice.

RE: Concrete Pile Caps to Steel Piles

Where I live (Spain) pile caps 1200 mm tall are quite common whatever the kind of the piles, maybe except when for very small loads. The pile cap will produce fixity on the received piles and so helps to keep the pilecap horizontal. For steel piles the vertical loads also need be passed in bond and bearing, or may be just in bond, what requires some embedment.

If you want to forfeit some of the required thickness for the bare surface of the piles in the embedment you may use studs, but I wouldn't recommend to do this to levels that turn the pile-cap too flexible.
