What is the purpose of strap beam & Tie beam connecting pile caps in Pile Foundation?.Some drawings mention that bottom level of pile cap and strap beam should be at same lavel but some drawing says top level should be at same level.Which one is correct?. What is the embedement length of strap beam bars into pile cap?

Are you possibly referring to a cantilever foundation. In cantilever foundation design two separate footings are interconnected by a reinforced concrete beam that is very stiff AND IS NOT SUPPORTED BY THE UNDERLYING SOIL! The purpose of the design is to force the soil reaction to be concentrated at a specific point. If you have a copy of either Urquahart and O'Rourke's Design of Concrete Structures or Elwyn E. Seelye's Data Book for Civil Engineers - Design, they give an example of such a design. Instead of bearing directly on soil as their examples do, it could be used to tie together pile caps. Just a thought - perhaps you could give some more detailed description of what your design entails.
