Example $12\mathrm{.}2$: Design reinforcement for the interior panel of the flat plate floor system shown in Fig. $12\mathrm{.}28.$ Assume that direct design method is applicable and the depth criterion in satisfied using a depth of $220$ mm $.$ Check the depth of slab for shear considering the effect of eccentric shear equal to $5\%$ of the direct shear for this interior panel. The other related data is as under:

Live load $=300kg\frac{s}{m^2},$ Floor finish and partitions $=150kg\frac{s}{m^2}$

$f_c^{\text{'}}=25$MPa,$f_y=300$MPa,$h=220mm$
