Shaft Resistance in Pile Foundations Formulas

Shaft Resistance is the load-bearing capacity of deep foundations such as piles or drilled shafts, derived from the frictional resistance along the sides of the shaft. And is denoted by Q _su. Shaft Resistance is usually measured using the Kilonewton for Force. Note that the value of Shaft Resistance is always positive.

FAQ

What is the Shaft Resistance?

Shaft Resistance is the load-bearing capacity of deep foundations such as piles or drilled shafts, derived from the frictional resistance along the sides of the shaft. Shaft Resistance is usually measured using the Kilonewton for Force. Note that the value of Shaft Resistance is always positive.

Can the Shaft Resistance be negative?

No, the Shaft Resistance, measured in Force cannot be negative.

What unit is used to measure Shaft Resistance?

Shaft Resistance is usually measured using the Kilonewton[kN] for Force. Newton[kN], Exanewton[kN], Meganewton[kN] are the few other units in which Shaft Resistance can be measured.
