Chapter 7, Problem 7.10QPP
After the footing in Problem 7.9 was built, the groundwater table rose to a depth of 0.5 m below the ground surface. Compute the new factor of safety against a bearing capacity failure. Compare it with the original design value of 2 and explain why it is different.

A circular footing has a radius of 4 ft. An engineering is looking for the stress in the soil 20 ft
below and 16 ft over from the center of the footing. What Influence Coefficient would the
engineer Use?
An 18 in square concrete column carries a factored ultimate compressive load of 640 k. It isto be supported on a 8 ft wide 12 ft long rectangular spread footing. Select appropriate valuesfor f′c and fy, then determine the required footing thickness and design the flexural reinforcingsteel. Show the results of your design in a sketch.
A 60 kip column is supported on a square footing with a length and base of 4 ft. Using the 2:1
Method, what is the increase in vertical stress (Ao₂) at a depth of 5 ft below the footing?
