Example on Design Shallow foundation A rectangular shallow foundation is to be placed at depth of 2 m below the ground surface of c, Φ soil and water table is at 1 m below the ground surface. Find the dimensions of the foundation for the column load is 3721 kN. Assume L = 1.5 B and factor of safety = 4

Example on two- way moments A square footing is 1.8 X 1.8 m with a 0.4 X 0.4 m square column. It is loaded with an axial load of 1800 kN and Mx = 450 kN • m; My = 360 kN • m. The soil has Φ = 36° and c = 20 kPa. The footing depth D = 1.8 m; the soil unit weight y = 18.00 kN/m³; the water table is at a depth of 6.1 m from the ground surface.
