The floor$-$beam$-$column system shown in Fig. $2$ is subjected to a superimposed DL $=30psf($excluding the self$-$wt$.$ of the floor slab and the beam$)$ and a superimposed $LL=60psf.$ Slabs A and $B$ are supported by edge beams but slab $C$ is cantilever. Design the combined slab system $($Slabs A$,$ B & C$).$ Use Ultimate Strength Design method $($USD$).$ Use all possible live load reductions. Given: $f_c^{\text{'}\text{'}}=4,000,f_y=60,000$ psi. Use ACI defined or any other moment coefficients.
