A five$-$span one$-$way slab is supported on $12-$in$.-$wide beam with center$-$to$-$center

spacing of $16ft.$ The slab carries a superimposed dead load of $10psf$ and a live load

of $100psf.$ Using $f_c^{\text{'}}=4000$ and $f_y=60,000,$ design the slab. Draw a cross

section showing the reinforcement. Use Normal weight concrete.

a$)$ Sketch the layout of the loading situation showing any relevant dimensions.

b$)$ Estimate the slab thickness.

c$)$ Compute the factored loads.

d$)$ Using ACI moment coefficients, determine the moments and Shears at the

respective locations for the beam.

e$)$ Compute the Shear capacity of the concrete section and state whether shear

reinforcement is required
