STEP 1: Convert Input(s) to Base Unit

Net Ultimate BC: 87 Kilonewton per Square Meter --> 87000 Pascal (Check conversion here)
Cohesion in Soil as Kilopascal: 1.27 Kilopascal --> 1270 Pascal (Check conversion here)
Bearing Capacity Factor dependent on Cohesion: 9 --> No Conversion Required
Effective Surcharge in KiloPascal: 45.9 Kilonewton per Square Meter --> 45900 Pascal (Check conversion here)
Bearing Capacity Factor dependent on Surcharge: 2.01 --> No Conversion Required
Unit Weight of Soil: 18 Kilonewton per Cubic Meter --> 18000 Newton per Cubic Meter (Check conversion here)
Bearing Capacity Factor dependent on Unit Weight: 1.6 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

B = (q_nu-((C*N_c)+(σ_s*(N_q-1))))/(0.5*γ*N_γ) --> (87000-((1270*9)+(45900*(2.01-1))))/(0.5*18000*1.6)

Evaluating ... ...

B = 2.02854166666667

STEP 3: Convert Result to Output's Unit

2.02854166666667 Meter --> No Conversion Required

FINAL ANSWER

2.02854166666667 ≈ 2.028542 Meter <-- Width 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.
