The floor$-$beam$-$column system shown in Fig. $1$ is subjected to a DL $=135$ psf $($including the self$-$wt$.$ of the floor slab and the beam$)$ and L$.$L$.-40psf.$ In addition to the distributed loading, beam AB is subjected to a concentrated $LL={25}^{\text{k}\text{i}\text{p}}$ as shown in Fig$\mathrm{.}1.$ Calculate the maximum moment developed in the beam $AB$ due to all possible loading on it$.$ Assume that beam $AB$ is simply supported. Use ACI Load Combinations for calculating the moment in the beam AB$.$ Use all possible live load reductions.
