Question
A square footing having a dimension of 2.5m x 2.5m is supported by a cohesionless soil with the following properties:
ϕ = 32∘
γ = 18 kN/m3
γsat = 20 kN/m3
The bottom of the footing is 1.5m below the ground surface. Use FS = 3 and γw = 9.81 kN/m3. Apply the general bearing capacity equation. GWT is at the bottom of the footing and load is applied at an eccentricity of 250mm along one side.
1. Determine the effective short dimension, B' (in m).
2. Determine the effective long dimension, L' (in m).
3. Determine the ultimate bearing capacity (in kPa).
4. Determine the magnitude of the gross allowable load applied eccentrically (in kN).
