a 39 in wide ,24 inch deep continuous footing supports a wall load of 12 kips/ft. this footing underlain by pure medium dense sand with D' = 31° and γ = 122 Lb/ft3. The ground water table is at a depth of 4 ft below the ground surface. Determine the allowable bearing capacity of this foundation using a factor of safety FS=2.5

1. Design a wall footing for the following conditions. Service dead load is 6 kips/ft, service live load is 8 kips/ft. Soil unit weight is 120 lb/ft?. Allowable soil pressure, qa is 4000 psf. The base of the footing is placed 3 ft below the ground surface. Wall is 12 in, thick. Geotechnical analyses have determined the width to be 4 ft. fe' = 3500 psi normal weight concrete, and fy = 60 ksi. Note: you don't need to design...
