"A rectangular reinforced concrete beam is to be designed to carry a distributed dead load of $2\mathrm{.}50$kip$\frac{s}{f}t,$ including the self$-$weight of the beam, and a distributed live load of $2\mathrm{.}00$kip$\frac{s}{f}t.$ In addition to the distributed loads above, there are $5-$kip point live loads, located at the midspan and beam quarter points $($three $[3]$ point loads total$).$ All loads should be considered as service loads and the beam is $16-$feet long $($simple span$).$ The beam width, $b,$ is $14in.$ and the total height, $h,$ is $28$ in$.$ Assume a cover distance of $3$ in$.($i$.$e$.,$ distance from the bottom face of the beam to the center of the tensile reinforcement$).$ Design the flexural reinforcement for the section. Use #$9$ bars for your longitudinal reinforcement. Use $f_c^{\text{'}}=4,000$ psi and $f_y=60,000$ psi.,"

Determine what the stirrup spacing should be at the critical section. Assume #$4$ stirrups are used. Use $f_c^{\text{'}}=4,000$ and $f_y=60,000.$ You are allowed to use the structural analysis from the midterm exam solution. $(25$ pts$.)$
