Dear Yaswanth,

Nice to hear about your work..skin friction along length of the pile can be calculated using two method..the one if you use embedded beam for simulating the pile then you could find axial force variation along the pile length directly in results output section. The axial force along the pile length is the skin friction..if you use volume element to simulate the pile in your model then you could get vertical and horizontal stress variation along length of the pile. With the use of vertical stress variation, calculate the skin friction using the equation Kx(sigmav)xtandelta Asi..ok all the best..

If the soil is clay, then how we will proceed to determine the skin friction?

Dear Mr.Naveen, thanks for interesting question.. the answer is if you have used embedded beam element to simulate the pile then directly you will get skin friction from axial force distribution along the beam. If you have used volume element then we need to obtain adhesion factor from vertical and horizontal stress distribution. With the use of vertical stress distribution you could estimate the strength increase or decrease. Another point you aware that the adhesion factor is constant value recommended by Tomilinson or Poulos and Davis can be used to calculate the friction capacity of the pile.

Mr. karthigeyan . S, I am very happy for your response. I hope this will help me out to complete my work.
