I intend to reinforce it for flexure only (shear not an issue). I plan to use top and bottom bars, with hooks to ensure the bars are developed. I often see small 'masses' of concrete detailed with 'skin reinforcing' all faces. This includes walls with 'U' bars at the top, providing a continuity of reinforcing from the inside to outside face.
The work is in a corrosive salt environment and I've of the opinion that added rebar is just going to cause problems.
I've not been able to any reference to using skin reinforcing for this type of application, that includes pile cap design. Any suggestions about why the small masses would be have skin reinforcing?
