A square footing is supporting a single interior column with a dimension of 12 in × 12 in. The column carries axial loads as follows: 100 kip dead load and 80 kip live load. Use normal-weight concrete with ?? ′ = 3 ksi, ?? = 60 ksi, and ?? = 5 ksf. The distance from the bottom of the footing to final grade is 5 ft. The height of the footing is 36 in and the concrete cover is 3.5 in. Unit weight of the soil is 100 pcf and unit weight of concrete is 150 pcf.

a) Determine the dimension of the footing (in 1.0-ft increment) and check if the depth is adequate.

b) Design the flexural reinforcement of the footing.

c) Design the dowel reinforcement.
