Q$\mathrm{.}1$Using the direct design method, design the typical interior flat$-$plate panel. The floor system consists of four panels in each direction with a panel size of $24*24$ ft$.$ All panels are supported by $22*22-$in$.$ columns, $11$ft long. The slab carries a uniform service live load of $120$psf and a service dead load that consists of $55$psf of floor finish in addition to the slab self$-$weight. Use normal$-$weight concrete with f$\text{'}*$ c $=4$ ksi and fy $=60$ ksi. ut
