Please Help

A. For the three cases shown determine the factored moment, Mu, at the critical section. The \( q_{u, \text { net }} \) value is \( 4.98 \mathrm{ksf} \). In all cases the footings have a width of 6 feet and a total depth of 2 feet. B. A normal weight reinforced concrete square footing \( (8 \mathrm{ft} x 8 \mathrm{ft}) \) has a total depth of 22 in. It carries a square column (20 in. \( x 20 \) in.). If \( q_{u, \text { net }} \) 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., \( f^{\prime}{ }_{c}=3,000 \mathrm{psi}, f_{y}=60,000 \mathrm{psi} \), and \( A_{s}=1 \mathrm{in}^{2} / \mathrm{ft} \). C. A normal weight reinforced concrete square footing \( (6 \mathrm{ft} x 6 \mathrm{ft}) \) has a total depth of 20 in. It carries a square column (20 in. \( x 20 \) in.). If \( P_{u}=144 \) kips determine the dowels needed to transfer the load between the column and the footing. Assume \( d=16 \) in., \( f^{\prime}{ }_{c}=3,500 \) psi and \( f_{y}=60,000 \) 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., \( f^{\prime}{ }_{c}=3,000 \mathrm{psi} \) and \( \mathrm{f}_{\mathrm{y}}=60,000 \mathrm{psi} \).
