Pile Design

Pile Design

Pile Design

(OP)
An engineer designed 4 piles for residential foundation on hillside home here in CA. He had designed it using enercalc with concrete column, then used enercalc for pole footing embedded in soil. I would like to learn how to calculate it by hand to understand pile design. Can anyone recommend a spreadsheet I can take a look at, or sample hand calcs they've done in the past for simple pile design? Thanks in advance.

RE: Pile Design

I understand what you mean when you say he used enercalc to design the concrete column. I usually use spcolumn for the same purpose, essentially to build the PM diagram for the column. Most concrete texts will go through the process for this by hand.

What I don't follow though is the use of the pole footing sizing for pile lateral loads. The lateral loads must be so small as to be applicable for the pole footing equations. The design for lateral loads is depenedent on the type of piles you have, free or fixed head (do the outer bars get developed into the pile cap?), and the lateral capacity/stiffness of the soil along the length of the pile.
