Cohesion of Soil given Round Footing and Bearing Capacity Solution

Follow our step by step solution on how to calculate Cohesion of Soil given Round Footing and Bearing Capacity?

FIRST Step Consider the formula

C r = \frac{q f - ((σ' \cdot N q) + (0.5 \cdot γ \cdot B \cdot N γ \cdot 0.6))}{1.3 \cdot N c}

Next Step Substitute values of Variables

∴

C r = \frac{60kPa - ((10Pa \cdot 2.01) + (0.5 \cdot 18kN/m³ \cdot 2m \cdot 1.6 \cdot 0.6))}{1.3 \cdot 1.93}

Next Step Convert Units

∴

C r = \frac{60000Pa - ((10Pa \cdot 2.01) + (0.5 \cdot 18000N/m³ \cdot 2m \cdot 1.6 \cdot 0.6))}{1.3 \cdot 1.93}

Next Step Prepare to Evaluate

∴

C r = \frac{60000 - ((10 \cdot 2.01) + (0.5 \cdot 18000 \cdot 2 \cdot 1.6 \cdot 0.6))}{1.3 \cdot 1.93}

Next Step Evaluate

∴

C r = 17018.6927062575Pa

Next Step Convert to Output's Unit

∴

C r = 17.0186927062575kPa

LAST Step Rounding Answer

∴

C r = 17.0187kPa
