1 Find the allowable axial force on column Q using the beari

1. Find the allowable axial force on column (Q) using the bearing capacity of granular soil under square spread footing. Use the material contained in Class 2 (January 31, 2018) Soil Density = 115 pcf (above water), 75 pcf (below water) Depth of foundation = 8 ft, Width of Footing = 6 ft Ground water encountered 5 ft below foundation 8 8

Solution

Use the bearing capacity formula and get a value allowable axial force

Those formula are..

Qp = [1+•2(Df÷B)]CNc + YDfNq+[1+•2 (Df÷B)]YBNy(because this is rectangular footing)

Where,

Qp = bearing capacity of soil

C= cohesion value

Y= unit weight of the soil

Df= depth of footing

B= width of footing
