Question
A square footing is to be designed to carry a total axial load of
5000kg. The bottom of the footing is 2.8m below the ground
surface, and the groundwater table is located at the bottom of
the footing. Take PDRY = 1860kg/m3 and PSAT = 1950kg/m3,
c = 1600kg/m2, Ø = 30degrees. Use the given Chart for the
90

70
determination of the bearing capacity factors.
a. Determine the dimension of the footing using a factor of
safety of 2.
b. Compute the ultimate bearing capacity of the soil in kPa.
Compute the net allowable bearing capacity of the soil.
