A 1.5 m square footing is founded at a depth of 1m (equal to the foundation thickness) in fine-grained soil with the following properties:
?dry = 20 kN/m3; ?sat = 22 kN/m3; ?u,k = 70 kPa; ?k′ = 10 kPa; ?k′ = 30°
The load on the footing is vertical but has a maximum eccentricity (?) of 250 mm from one axis (Hint: B- = B − 2e). If the water table is at the foundation level, determine the design bearing resistance of the footing for
a. short-term condition
b. long-term condition
A square footing 2.5 m X 2.5 m is built on a homogeneous bed of sand
of density 19 kN/m3
having an angle of shearing resistance of 36o
. The
depth of foundation is 1.5 m below the ground surface. Calculate the
safe load that can be applied on the footing with a factor of safety of 3.
A long footing 2 m wide is located in the level area at the top of a long, 45° slope where clay soils exist. The slope height is greater than the footing width. The soil unit weight is 17.5 kN/m3, and the cohesion shear strength is 65 kPa. The D/B ratio is 1, and the b/B ratio is also 1. What loading can be imposed onto the footing per meter of length (using a factor of safety of 3 with the bearing capacity equation appropriate for footings along the top of slopes)?
