Q Consider the continuous the one$-$way floor system shown below. Assume the floor is to be designed for a live load of $80$ psf and a superimposed dead load $($SDL$)$ of $20$ psf$.$ Use f$\text{'}$c of $4000$ psi and Grade $60$ksi steel.

a$)$ Calculate the thickness of the slab based on the deflection requirements $($Hint: both spans are one$-$end continuous$)$

b$)$ Calculate the total dead load, live load, and factored loads acting on a typical $1ft-$strip of the slab.

c$)$ Use the ACI moment coefficients to find the design moments at sections $1,2,$ and $3$

d$)$ Design the reinforcement at the sections $1,2,$ and $3.($for initial As$,$ assume jd $=0\mathrm{.}95d)$

e$)$ Design the thermal and shrinkage reinforcement for the slab.

Make all the necessary checks for strength, ductility, and reinforcement arrangements.
