This formula uses 4 Variables
Variables Used
Net Safe Bearing Capacity in Soil - (Measured in Pascal) - Net Safe Bearing Capacity in Soil is the net ultimate bearing capacity divided by factor of safety.
Ultimate Bearing Capacity in Soil - (Measured in Pascal) - Ultimate Bearing Capacity in Soil is defined as the minimum gross pressure intensity at the base of the foundation at which the soil fails in shear.
Effective Surcharge in KiloPascal - (Measured in Pascal) - Effective Surcharge in KiloPascal also called as surcharge load refers to the vertical pressure or any load that acts over the ground surface additional to basic earth pressure.
Factor of Safety in Bearing Capacity of Soil - Factor of Safety in Bearing Capacity of Soil expresses how much stronger a soil is than it needs to be for an intended load.
STEP 1: Convert Input(s) to Base Unit
Ultimate Bearing Capacity in Soil: 127.8 Kilopascal --> 127800 Pascal (Check conversion here)
Effective Surcharge in KiloPascal: 45.9 Kilonewton per Square Meter --> 45900 Pascal (Check conversion here)
Factor of Safety in Bearing Capacity of Soil: 2.8 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
qnsa = (qfcs)/FOS --> (127800-45900)/2.8
Evaluating ... ...
qnsa = 29250
STEP 3: Convert Result to Output's Unit
29250 Pascal -->29.25 Kilonewton per Square Meter (Check conversion here)
FINAL ANSWER
29.25 Kilonewton per Square Meter <-- Net Safe Bearing Capacity in Soil
