Depth of Footing given Bearing Capacity Factor and Width of Footing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Depth of Footing = (Net Ultimate Bearing Capacity-((Cohesion of Soil*Bearing Capacity Factor dependent on Cohesion)+(0.5*Unit Weight of Soil*Width of Footing*Bearing Capacity Factor dependent on Unit Weight)))/(Unit Weight of Soil*(Bearing Capacity Factor dependent on Surcharge-1))
D = (q_nf-((C_s*N_c)+(0.5*γ*B*N_γ)))/(γ*(N_q-1))
This formula uses 8 Variables

Variables Used

STEP 1: Convert Input(s) to Base Unit

Net Ultimate Bearing Capacity: 150 Kilonewton per Square Meter --> 150000 Pascal (Check conversion here)
Cohesion of Soil: 5 Kilopascal --> 5000 Pascal (Check conversion here)
Bearing Capacity Factor dependent on Cohesion: 9 --> No Conversion Required
Unit Weight of Soil: 18 Kilonewton per Cubic Meter --> 18000 Newton per Cubic Meter (Check conversion here)
Width of Footing: 2 Meter --> 2 Meter No Conversion Required
Bearing Capacity Factor dependent on Unit Weight: 1.6 --> No Conversion Required
Bearing Capacity Factor dependent on Surcharge: 2.01 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = (q_nf-((C_s*N_c)+(0.5*γ*B*N_γ)))/(γ*(N_q-1)) --> (150000-((5000*9)+(0.5*18000*2*1.6)))/(18000*(2.01-1))

Evaluating ... ...

D = 4.19141914191419

STEP 3: Convert Result to Output's Unit

4.19141914191419 Meter --> No Conversion Required

FINAL ANSWER

4.19141914191419 ≈ 4.191419 Meter <-- Depth of Footing

What is Footing?

Footings are an important part of foundation construction. They are typically made of concrete with rebar reinforcement that has been poured into an excavated trench. The purpose of footings is to support the foundation and prevent settling. Footings are especially important in areas with troublesome soils.
