A. For the three cases shown determine the factored moment, Mu, at the critical section. The \( \mathrm{qu}_{u, n e t} \) value is \( 4.98 \mathrm{ksf} \). In all cases the footings have a width of 6 feet and a total depth of 2 feet. \( \times 18 \) in. ete in B. A normal weight reinforced concrete square footing \( (8 \mathrm{ft} \times 8 \mathrm{ft}) \) has a total depth of 22 in. It carries a square column (20 in. \( \times 20 \) in.). If \( q_{u, n e t} \) value is \( 5.24 \mathrm{ksf} \) determine if the footing can carry the shear (Two-way and one-way) without shear reinforcement. Assume \( d=18 \) in., \( f_{c}^{\prime}=3,000 \) psi, \( f_{y}=60,000 \mathrm{psi} \), and \( A_{s}=1 \) in \( ^{2} / \mathrm{ft} \). C. A normal weight reinforced concrete square footing \( (6 \mathrm{ft} \times 6 \mathrm{ft}) \) has a total depth of \( 20 \mathrm{in} \). It carries a square column ( \( 20 \mathrm{in} . \times 20 \) in.). If \( P_{u}=144 \) kips determine the dowels needed to transfer the load between the column and the footing. Assume \( d=16 \) in., \( f_{c} c=3,500 \) psi and \( f_{y}=60,000 \mathrm{psi} \). 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., \( f_{c}^{\prime}=3,000 \mathrm{psi} \) and \( f_{Y}=60,000 \mathrm{psi} \).
