A continuous strip footing is to be located concentrically under a 300 mm wall that delivers service loads D = 360 kN/m and L= 220 kN/m to the top of the footing. The bottom of the footing will be 1.2 m below the final ground surface. The soil has a density of 20Kn/m3 and allowable bearing capacity of 280 Kn/m2. Materials strengths are fc’ =21 MPa and fy = 276 MPa. *Give an on-scale schematic structural detail
