The underlying soil is a well-graded sand with c′ = 0, f′ = 36°, g = 126 lb/ft3, with a verydeep groundwater table. Using LRFD, design a rectangular footing to meet the ultimate limitstates using a resistance factor of 0.45. Assuming the average CPT tip resistance of the sand is300 kg/cm2, check to see if your design meets serviceability limits. Adjust the design as needed.
