Assume we are building a foundation on a saturated clay deposit with an average undrainedshear strength of 2,000 lb/ft2 and a COV of 0.2. The average unit weight for the soil is102 lb/ft3 with a COV of 0.05. What is the mean short-term nominal bearing capacity of acontinuous footing founded at a depth of 5 ft? What is the probability that the nominal bearing capacity of a certain footing would be less than 75 percent of the mean nominal bearing capac-ity if the undrained shear strength and unit weight are normally distributed and independent?

Question
Assume we are building a foundation on a saturated clay deposit with an average undrained
shear strength of 2,000 lb/ft2 and a COV of 0.2. The average unit weight for the soil is
102 lb/ft3 with a COV of 0.05. What is the mean short-term nominal bearing capacity of a
continuous footing founded at a depth of 5 ft? What is the probability that the nominal bearing
capacity of a certain footing would be less than 75 percent of the mean nominal bearing capac-
ity if the undrained shear strength and unit weight are normally distributed and independent?
