Design a square reinforced concrete footing to support a 20-inch square tied concrete column at the edge of the building as shown below. Also check development length and force transfer in the column and at the footing. Draw the reinforcement pattern. Use a footing thickness of 24". Assume the following design conditions: -service dead load= 270 kips -service live load= 135 kips -allowable soil pressure (q.)= 5000 psf -fe for the column= 5000 psi -f for the footing= 3000 psi -fy= 60000 psi -longitudinal column steel consists of #8 bars -all reinforcement is uncoated -unit weight of the soil is 125 lb/ft3 -normal weight concrete Finished ground line 20" square column

Design a square reinforced concrete footing to support a 20-inch square tied concrete
column at the edge of the building as shown below. Also check development length
and force transfer in the column and at the footing. Draw the reinforcement pattern.
Use a footing thickness of 24".
Assume the following design conditions:
-service dead load= 270 kips
-service live load= 135 kips
-allowable soil pressure (q)= 5000 psf
-f. for the column= 5000 psi
-f for the footing= 3000 psi
-fy= 60000 psi
-longitudinal column steel consists of #8 bars
-all reinforcement is uncoated
-unit weight of the soil is 125 1lb/ft3
-normal weight concrete
Finished ground line
20" square column
Y = 125 lb/ft³
