C. A normal weight reinforced concrete square footing (6ft x 6ft) has a total depth of 20 in. It carries a square column (20 in. x 20 in.). If P, = 144 kips determine the dowels needed to transfer the load between the column and the footing. Assume d = 16 in., f'c = 3,500 psi and fy = 60,000 psi. D. For the concrete footing and concrete column in part A, determine the tension steel to carry the calculated moment. Assume the footing to be square, d = 20 in., f'c = 3,000 psi and fy = 60,000 psi.

B. A normal weight reinforced concrete square footing (8ft x 8ft) has a total depth of 22 in.
It carries a square column (20 in. x 20 in.). If qu,net value is 5.24 ksf determine if the
footing can carry the shear (Two-way and one-way) without shear reinforcement.
Assume d = 18 in., f'c = 3,000 psi and fy = 60,000 psi.
C. A normal weight reinforced concrete square footing (6ft x 6ft) has a total depth of 20 in.
It carries a square column (20 in. x 20 in.). If Pų = 144 kips determine the dowels needed
to transfer the load between the column and the footing. Assume d = 16 in., f'c = 3,500
psi and fy = 60,000 psi.
D. For the concrete footing and concrete column in part A, determine the tension steel to
carry the calculated moment. Assume the footing to be square, d = 20 in., f'c = 3,000 psi
and fy = 60,000 psi.
