Net Ultimate Bearing Capacity given Depth and Width of Footing Solution

Follow our step by step solution on how to calculate Net Ultimate Bearing Capacity given Depth and Width of Footing?

FIRST Step Consider the formula

q nf = ((C s \cdot N c) + ((γ \cdot D) \cdot (N q - 1)) + (0.5 \cdot γ \cdot B \cdot N γ))

Next Step Substitute values of Variables

∴

q nf = ((5kPa \cdot 9) + ((18kN/m³ \cdot 1.01m) \cdot (2.01 - 1)) + (0.5 \cdot 18kN/m³ \cdot 2m \cdot 1.6))

Next Step Convert Units

∴

q nf = ((5000Pa \cdot 9) + ((18000N/m³ \cdot 1.01m) \cdot (2.01 - 1)) + (0.5 \cdot 18000N/m³ \cdot 2m \cdot 1.6))

Next Step Prepare to Evaluate

∴

q nf = ((5000 \cdot 9) + ((18000 \cdot 1.01) \cdot (2.01 - 1)) + (0.5 \cdot 18000 \cdot 2 \cdot 1.6))

Next Step Evaluate

∴

q nf = 92161.8Pa

LAST Step Convert to Output's Unit

∴

q nf = 92.1618kN/m²
