We are interested in the forces at a footing due to dead, live, and earthquake loads. The horizontal forces are 0.8 for dead, 1.0 for live, and 4.4 for earthquake. The vertical forces are 2.6 for dead, 3.5 for live, and 3.9 for earthquake. For vertical forces, positive indicates compression and negative indicates uplift. Apply all the relevant load combinations. All forces are in kips. Determine the largest uplift force in kips to two decimals. Since uplift is negative, provide a negative answer. If your calculations show that there is no uplift, enter zero. × -10.52

A 600 mm square interior column, reinforced with eight No.25 bars of Grade 420, supports a dead load of 866 KN and a live load of 577.33 KN. Assume that a live load reduction of 30% may be allowed at foundation level. The foundation is to be placed at a depth of 1m where the allowable bearing capacity is 110 KPa. The average density of the backfill material and the footing concrete together may be taken as 2100 Kg/Cu.m, while the filling from ground to plinth level is to be 0.5m of material with average density of 1900 Kg/Cu.m. Design a square footing using fc’=20 MPa, fy for foundation steel=300 MPa and fy for dowel steel=420 MPa.
