Question

A column carrying a vertical downward ultimate factored load of 1,500 kN is to be supported
on a 1 m deep square spread footing. The soil beneath this footing is an undrained clay with
su = 150 kPa and g = 18.1 kN/m3

. The groundwater table is below the bottom of the footing.
Using the LRFD method, compute the required width B. Assume the geotechnical resistance
factor is 0.5.
