Shaft Resistance using Allowable Load and Safety Factor Solution

STEP 0: Pre-Calculation Summary
Formula Used
Shaft Resistance = (Factor of Safety in Soil Mechanics*Allowable Load)-Toe Resistance
Q su = (Fs*Pallow)-Q bu
This formula uses 4 Variables
Variables Used
Shaft Resistance - (Measured in Newton) - Shaft Resistance is the load resisted by a pile's shaft.
Factor of Safety in Soil Mechanics - Factor of Safety in Soil Mechanics expresses how much stronger a system is than it needs to be for an intended load.
Allowable Load - (Measured in Newton) - Allowable load is the maximum working load that can be applied on the structure.
Toe Resistance - (Measured in Newton) - Toe Resistance is the load resisted by the toe of a pile.
STEP 1: Convert Input(s) to Base Unit
Factor of Safety in Soil Mechanics: 2.8 --> No Conversion Required
Allowable Load: 10 Kilonewton --> 10000 Newton (Check conversion here)
Toe Resistance: 10.23 Kilonewton --> 10230 Newton (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Q su = (Fs*Pallow)-Q bu --> (2.8*10000)-10230
Evaluating ... ...
Q su = 17770
STEP 3: Convert Result to Output's Unit
17770 Newton -->17.77 Kilonewton (Check conversion here)
FINAL ANSWER
17.77 Kilonewton <-- Shaft Resistance
(Calculation completed in 00.004 seconds)

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 Soil Mechanics*Allowable Load)-Toe Resistance
Toe Resistance using Allowable Load and Safety Factor
Go Toe Resistance = (Allowable Load*Factor of Safety in Soil Mechanics)-Shaft Resistance
Allowable Load for given Safety Factor
Go Allowable Load = (Shaft Resistance+Toe Resistance)/Factor of Safety in Soil Mechanics
Pile Capacity
Go Pile Capacity = Shaft Resistance+Toe Resistance
