Effective Surcharge given Bearing Capacity for Square Footing Solution

Follow our step by step solution on how to calculate Effective Surcharge given Bearing Capacity for Square Footing?

FIRST Step Consider the formula

σ s = q f - ((C \cdot N c) \cdot (1 + 0.3 \cdot (\frac{B}{L})))

Next Step Substitute values of Variables

∴

σ s = 60kPa - ((1.27kPa \cdot 9) \cdot (1 + 0.3 \cdot (\frac{2m}{4m})))

Next Step Convert Units

∴

σ s = 60000Pa - ((1270Pa \cdot 9) \cdot (1 + 0.3 \cdot (\frac{2m}{4m})))

Next Step Prepare to Evaluate

∴

σ s = 60000 - ((1270 \cdot 9) \cdot (1 + 0.3 \cdot (\frac{2}{4})))

Next Step Evaluate

∴

σ s = 46855.5Pa

LAST Step Convert to Output's Unit

∴

σ s = 46.8555kN/m²
