Question
A 5 ft square, 2 ft deep spread footing is subjected to a concentric vertical load of 60 k and an
overturning moment of 30 ft-k. The overturning moment acts parallel to one of the sides of the
footing, and the top of the footing is flush with the ground surface and the groundwater table
is at a depth of 20 ft below the ground surface. Determine whether the resultant force acts
within the middle third of the footing, compute the minimum and maximum bearing pressures
and show the distribution of bearing pressure in a sketch. Determine the size of the equivalent
uniformly loaded footing and compute the equivalent bearing pressure.
