Ultimate Bearing Capacity given Depth of Footing Solution

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

FIRST Step Consider the formula

q f = q net' + (γ \cdot D footing)

Next Step Substitute values of Variables

∴

q f = 5.3kN/m² + (18kN/m³ \cdot 2.54m)

Next Step Convert Units

∴

q f = 5300Pa + (18000N/m³ \cdot 2.54m)

Next Step Prepare to Evaluate

∴

q f = 5300 + (18000 \cdot 2.54)

Next Step Evaluate

∴

q f = 51020Pa

LAST Step Convert to Output's Unit

∴

q f = 51.02kPa
