What is Skin-Friction?
Skin-Friction is the soil resistance acting along a pile shaft, caused by soil moving
relative to the pile shaft; it must be less than, or equal to, the shaft capacity.
Negative skin friction – Soil resistance acting downward along a pile shaft,
caused by soil moving downward relative to the pile shaft.
Positive skin friction – Soil resistance acting upward along a pile shaft, caused
by soil moving upward relative to the pile shaft
How to Calculate Average Ultimate Skin-Friction Stress in Tension on Failure Plane?
Average Ultimate Skin-Friction Stress in Tension on Failure Plane calculator uses Skin Friction Stress in Soil Mechanics = ((Ultimate Resistance-Weight of Soil-Shaft Weight in Soil Mechanics)/(pi*Length of Soil Section)) to calculate the Skin Friction Stress in Soil Mechanics, The Average Ultimate Skin-Friction Stress in Tension on Failure Plane is defined as a function of ultimate resistance, weight of soil contained within the failure plane and the weight of the shaft. Skin Friction Stress in Soil Mechanics is denoted by f ut symbol.
