Friction Angle on Pile Skin

The friction angle δ is calculated on the basis of the following graph according to the internal friction angle φef, the volume of the pile, and its type (according to the corresponding curve):

  • curve "a": steel pipes
  • curve "b": wooden piles
  • curve "c": concrete prefabricated piles
  • curve "f": other steel cross-sections, CFA, and bored piles

Relationship between δ/φ and pile volume

Pile skin friction angle δ can be also inputted manually in the "Adding new soils" dialog window.
