Pile Capacity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pile Capacity = Shaft Resistance+Toe Resistance
Q _u = Q _su+Q _bu
This formula uses 3 Variables

Variables Used

Pile Capacity - (Measured in Newton) - Pile Capacity is the maximum load which it can carry without failure or excessive settlement of the ground.
Shaft Resistance - (Measured in Newton) - 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.
Toe Resistance - (Measured in Newton) - Toe Resistance is the capacity of the soil at the base or toe of a structure (such as a retaining wall, foundation, or slope) to resist sliding or overturning.

STEP 1: Convert Input(s) to Base Unit

Shaft Resistance: 17.77 Kilonewton --> 17770 Newton (Check conversion here)
Toe Resistance: 10.23 Kilonewton --> 10230 Newton (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q _u = Q _su+Q _bu --> 17770+10230

Evaluating ... ...

Q _u = 28000

STEP 3: Convert Result to Output's Unit

28000 Newton -->28 Kilonewton (Check conversion here)

FINAL ANSWER

28 Kilonewton <-- Pile Capacity

< 5 Axial Load Capacity of Single Piles Calculators

Allowable Load using Safety Factors

Go Allowable Load = (Shaft Resistance/Factor of Safety F1)+(Toe Resistance/Factor of Safety F2)

Shaft Resistance using Allowable Load and Safety Factor

Go Shaft Resistance = (Factor of Safety in Pile Foundation*Allowable Load)-Toe Resistance

Toe Resistance using Allowable Load and Safety Factor

Go Toe Resistance = (Allowable Load*Factor of Safety in Pile Foundation)-Shaft Resistance

Allowable Load for given Safety Factor

Go Allowable Load = (Shaft Resistance+Toe Resistance)/Factor of Safety in Pile Foundation

Pile Capacity

Go Pile Capacity = Shaft Resistance+Toe Resistance

Pile Capacity Formula

Pile Capacity = Shaft Resistance+Toe Resistance
Q _u = Q _su+Q _bu

What is Pile Capacity?

Pile Capacity is the maximum load which a pile can carry without failure or excessive settlement of the ground. The bearing capacity of a pile depends primarily on 3 factors as given below,Type of soil through which pile is embedded, Method of pile installation, Pile dimension (cross section & length of pile).

How to Calculate Pile Capacity?

Pile Capacity calculator uses Pile Capacity = Shaft Resistance+Toe Resistance to calculate the Pile Capacity, The Pile Capacity formula is defined as the sum of shaft resistance and the toe resistance. Pile Capacity is the maximum load which a pile can carry without failure. Pile Capacity is denoted by Q _u symbol.

How to calculate Pile Capacity using this online calculator? To use this online calculator for Pile Capacity, enter Shaft Resistance (Q _su) & Toe Resistance (Q _bu) and hit the calculate button. Here is how the Pile Capacity calculation can be explained with given input values -> 0.028 = 17770+10230.

FAQ

What is Pile Capacity?

The Pile Capacity formula is defined as the sum of shaft resistance and the toe resistance. Pile Capacity is the maximum load which a pile can carry without failure and is represented as Q _u = Q _su+Q _bu or Pile Capacity = Shaft Resistance+Toe 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 & Toe Resistance is the capacity of the soil at the base or toe of a structure (such as a retaining wall, foundation, or slope) to resist sliding or overturning.

How to calculate Pile Capacity?

The Pile Capacity formula is defined as the sum of shaft resistance and the toe resistance. Pile Capacity is the maximum load which a pile can carry without failure is calculated using Pile Capacity = Shaft Resistance+Toe Resistance. To calculate Pile Capacity, you need Shaft Resistance (Q _su) & Toe Resistance (Q _bu). With our tool, you need to enter the respective value for Shaft Resistance & Toe Resistance and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
