Safe Bearing Capacity given Net Ultimate Bearing Capacity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Safe Bearing Capacity = (Net Ultimate Bearing Capacity/Factor of Safety in Bearing Capacity of Soil)+(Unit Weight of Soil*Depth of Footing in Soil)
q_sa = (q_net'/FOS)+(γ*D_footing)
This formula uses 5 Variables

Variables Used

Safe Bearing Capacity - (Measured in Pascal) - Safe Bearing Capacity is the maximum pressure which the soil can carry safely without risk of shear failure.
Net Ultimate Bearing Capacity - (Measured in Pascal) - Net Ultimate Bearing Capacity is the maximum load per unit area that a soil can withstand without failure under the conditions imposed by the presence of groundwater.
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.
Unit Weight of Soil - (Measured in Newton per Cubic Meter) - Unit Weight of Soil mass is the ratio of the total weight of soil to the total volume of soil.
Depth of Footing in Soil - (Measured in Meter) - Depth of Footing in Soil is the depth at which the foundation of a structure is placed below the ground surface. This is crucial for ensuring the stability of the structure.

STEP 1: Convert Input(s) to Base Unit

Net Ultimate Bearing Capacity: 5.3 Kilonewton per Square Meter --> 5300 Pascal (Check conversion here)
Factor of Safety in Bearing Capacity of Soil: 2.8 --> No Conversion Required
Unit Weight of Soil: 18 Kilonewton per Cubic Meter --> 18000 Newton per Cubic Meter (Check conversion here)
Depth of Footing in Soil: 2.54 Meter --> 2.54 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

q_sa = (q_net'/FOS)+(γ*D_footing) --> (5300/2.8)+(18000*2.54)

Evaluating ... ...

q_sa = 47612.8571428571

STEP 3: Convert Result to Output's Unit

47612.8571428571 Pascal -->47.6128571428571 Kilonewton per Square Meter (Check conversion here)

FINAL ANSWER

47.6128571428571 ≈ 47.61286 Kilonewton per Square Meter <-- Safe Bearing Capacity

Ultimate Bearing Capacity of Soil under Long Footing at Surface of Soil

Go Ultimate Bearing Capacity = ((Prandtls Cohesion/tan(Angle of Internal Friction of Soil))+(0.5*Dry Unit Weight of Soil*Width of Footing*sqrt(Coefficient of Passive Pressure))*(Coefficient of Passive Pressure*exp(pi*tan(Angle of Internal Friction of Soil))-1))

Net Ultimate Bearing Capacity given Ultimate Bearing Capacity

Go Net Ultimate Bearing Capacity of Soil = Ultimate Bearing Capacity-Effective Surcharge in Kilo Pascal

Ultimate Bearing Capacity

Go Ultimate Bearing Capacity = Net Ultimate Bearing Capacity of Soil+Effective Surcharge in Kilo Pascal

Effective Surcharge given Depth of Footing

Go Effective Surcharge in Kilo Pascal = Unit Weight of Soil*Depth of Footing

Safe Bearing Capacity given Net Ultimate Bearing Capacity Formula

Safe Bearing Capacity = (Net Ultimate Bearing Capacity/Factor of Safety in Bearing Capacity of Soil)+(Unit Weight of Soil*Depth of Footing in Soil)
q_sa = (q_net'/FOS)+(γ*D_footing)
