How to design a pile cap for a single pile? explain with a drawing?

Answer 1

Hi, let me tell you before you proceed to read further my answer, i am not answering your question rightaway, but shall share some details with you, presuming you are not aware of them....

Usually, pile cap is designed for a cluster of piles [more than one atleast] or 'Pile Groups' as it is called. The reason being the strengthening of the shaft and the load carrying capacity enhances with more piles than one.

Secondly, as regards to your question i think you are designing for a civil building not a bridge structure[otherwise your question will be totally wrong], in which case, i would suggest you do the design and analysis [i mean finding pile cap resistance and deflection, which many people avoid because of its difficulty] using Staad.Pro or other FEM softwares.

I am providing a link here, see if you find useful. in the meanwhile, let me try to get you a down to earth explanation and understanding for pile cap designs from my collection.
