Net Safe Bearing Capacity given Ultimate Bearing Capacity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Net Safe Bearing Capacity = (Ultimate Bearing Capacity of Soil-Effective Surcharge in Kilo Pascal)/Factor of Safety in Bearing Capacity of Soil
q_nsa' = (q_fc-σ_s)/FOS
This formula uses 4 Variables

Variables Used

Net Safe Bearing Capacity - (Measured in Pascal) - Net Safe Bearing Capacity is the maximum allowable pressure that can be applied to the soil beneath a structure without risking shear failure or excessive settlement.
Ultimate Bearing Capacity of Soil - (Measured in Pascal) - Ultimate Bearing Capacity of 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 Kilo Pascal - (Measured in Pascal) - Effective Surcharge in Kilo Pascal 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 of Soil: 127.8 Kilopascal --> 127800 Pascal (Check conversion here)
Effective Surcharge in Kilo Pascal: 0.45 Kilonewton per Square Meter --> 450 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

q_nsa' = (q_fc-σ_s)/FOS --> (127800-450)/2.8

Evaluating ... ...

q_nsa' = 45482.1428571429

STEP 3: Convert Result to Output's Unit

45482.1428571429 Pascal -->45.4821428571429 Kilonewton per Square Meter (Check conversion here)

FINAL ANSWER

45.4821428571429 ≈ 45.48214 Kilonewton per Square Meter <-- Net Safe Bearing Capacity
