Unit Weight of Soil for Rectangular Footing given Shape Factor Solution

Follow our step by step solution on how to calculate Unit Weight of Soil for Rectangular Footing given Shape Factor?

FIRST Step Consider the formula

γ = \frac{q fc - (((C \cdot N c) \cdot (1 + 0.3 \cdot (\frac{B}{L}))) + (σ s \cdot N q))}{(0.5 \cdot B \cdot N γ) \cdot (1 - 0.2 \cdot (\frac{B}{L}))}

Next Step Substitute values of Variables

∴

γ = \frac{127.8kPa - (((1.27kPa \cdot 9) \cdot (1 + 0.3 \cdot (\frac{2m}{4m}))) + (45.9kN/m² \cdot 2.01))}{(0.5 \cdot 2m \cdot 1.6) \cdot (1 - 0.2 \cdot (\frac{2m}{4m}))}

Next Step Convert Units

∴

γ = \frac{127800Pa - (((1270Pa \cdot 9) \cdot (1 + 0.3 \cdot (\frac{2m}{4m}))) + (45900Pa \cdot 2.01))}{(0.5 \cdot 2m \cdot 1.6) \cdot (1 - 0.2 \cdot (\frac{2m}{4m}))}

Next Step Prepare to Evaluate

∴

γ = \frac{127800 - (((1270 \cdot 9) \cdot (1 + 0.3 \cdot (\frac{2}{4}))) + (45900 \cdot 2.01))}{(0.5 \cdot 2 \cdot 1.6) \cdot (1 - 0.2 \cdot (\frac{2}{4}))}

Next Step Evaluate

∴

γ = 15553.125N/m³

Next Step Convert to Output's Unit

∴

γ = 15.553125kN/m³

LAST Step Rounding Answer

∴

γ = 15.5531kN/m³
