Chapter 2, Problem 2.9QPP

We wish to design a shallow foundation with a probability of failure of 10 3 . The footing supports a column carrying a dead load with a mean of 30 k and COV of 0.05 and a live load with a mean of 10 k and COV of 0.15. Based on the uncertainty of soil properties and our analysis method, we estimate the COV of the foundation capacity to be 0.2. For what mean capacity does the foundation need to be designed? Assume both loads and capacity are normally distributed.
