Width of Footing given Bearing Capacity for Local Shear Failure Solution

Follow our step by step solution on how to calculate Width of Footing given Bearing Capacity for Local Shear Failure?

FIRST Step Consider the formula

B = \frac{q fc - (((\frac{2}{3}) \cdot C \cdot N c) + (σ s \cdot N q))}{0.5 \cdot N γ \cdot γ}

Next Step Substitute values of Variables

∴

B = \frac{127.8kPa - (((\frac{2}{3}) \cdot 1.27kPa \cdot 9) + (45.9kN/m² \cdot 2.01))}{0.5 \cdot 1.6 \cdot 18kN/m³}

Next Step Convert Units

∴

B = \frac{127800Pa - (((\frac{2}{3}) \cdot 1270Pa \cdot 9) + (45900Pa \cdot 2.01))}{0.5 \cdot 1.6 \cdot 18000N/m³}

Next Step Prepare to Evaluate

∴

B = \frac{127800 - (((\frac{2}{3}) \cdot 1270 \cdot 9) + (45900 \cdot 2.01))}{0.5 \cdot 1.6 \cdot 18000}

Next Step Evaluate

∴

B = 1.93895833333333m

LAST Step Rounding Answer

∴

B = 1.939m
