Problem $2.$ Design the positive and negative reinforcement for panels I, II$,$ and III at all critical locations for the continuous slab shown below using the ACI moment coefficients. Use fy $=60,000$ and $f^{\text{'}}c=4,000.$ Check that $Mn$ is not greater than $1\mathrm{.}2.$ Assume normal weight concrete is used. In addition to its own weight, the slab is loaded with $D=40$ psf and $L=100$ psf$.$ Use a minimum bar cover of $\frac{3}{4}in.$ Solid and dashed lines represent beams $10in.$ wide and $30in.$ tall $($including slab$).$ The floor is supported by $14in.$ diameter circular columns.
