Question
A surface reinforced concrete strip foundation, unit weight 24 kN/m³, is
2 m wide, 0.5 m thick and will be subjected to a uniform normal pressure,
p, of mean value 500 kN/m² and coefficient of variation, Vp, of 6%.
The soil is cohesionless.
Unit weight:
mean = 18 kN/m³; V₁ = 5%
Angle of friction: mean = 40°; V₂ = 2.5%
Determine the reliability index against bearing capacity failure.
