Toe Resistance using Allowable Load and Safety Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Toe Resistance = (Allowable Load*Factor of Safety in Soil Mechanics)-Shaft Resistance
Q _bu = (P_allow*F_s)-Q _su
This formula uses 4 Variables

Variables Used

Toe Resistance - (Measured in Newton) - Toe Resistance is the load resisted by the toe of a pile.
Allowable Load - (Measured in Newton) - Allowable load is the maximum working load that can be applied on the structure.
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.
Shaft Resistance - (Measured in Newton) - Shaft Resistance is the load resisted by a pile's shaft.

STEP 1: Convert Input(s) to Base Unit

Allowable Load: 10 Kilonewton --> 10000 Newton (Check conversion here)
Factor of Safety in Soil Mechanics: 2.8 --> No Conversion Required
Shaft Resistance: 10.65 Kilonewton --> 10650 Newton (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q _bu = (P_allow*F_s)-Q _su --> (10000*2.8)-10650

Evaluating ... ...

Q _bu = 17350

STEP 3: Convert Result to Output's Unit

17350 Newton -->17.35 Kilonewton (Check conversion here)

FINAL ANSWER

17.35 Kilonewton <-- Toe Resistance

(Calculation completed in 00.004 seconds)
