Geotechnical square foundation design
1. A square footing is subjected to a vertical load of 50,000 lbs and a moment of 25,000 lb-ft. The depth of the foundation is 4 ft. The water table is at the base of the footing. The soil above the base of the footing has y-100 pcf and a friction angle of 30°. The soil below the base of the footing has a Ysat 120 pcf, a friction angle of 20° and c-100 psf. Find...
