Question: 7 . 5 A column carrying a vertical downward ultimate factored load of 1 , 5 0 0 k N is to be supported on

7.5 A column carrying a vertical downward ultimate factored load of 1,500kN is to be supported
on a 1 m deep square spread footing. The soil beneath this footing is an undrained clay with
su=150kPa and =18.1kNm3. 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.
