Given:

Refer to Figure $1.$

Five floors. Floor height, h$1=3\mathrm{.}60$m$.$

L$1=7\mathrm{.}00////$ L$2=6\mathrm{.}50$ M

Concrete compressive strength, f$$c$=28$MPa.

Reinforcing steel yield strength, fy$=420$MPa.

Super imposed dead load on slab$=4\mathrm{.}5$kN$/$m$2.$

Live load on slab, WL$=3\mathrm{.}0$kN$/$m$2.$

Exterior walls are masonry, Wwall$=20\mathrm{.}0$kN$/$m$.$

Soil allowable bearing capacity, qall$=470$kN$/$m$2.$

Design the slab system as $($Hint: The preliminary column size can be $300$mm x $300$mm$)$:

$$ One$-$way solid slab.

$$ One$-$way ribbed slab with hidden beams.

Design the columns and the footings for solid slab system. Hint: Use the ACI coefficients in the structural analysis of slab strips and beams. Introduce professional structural design report and drawings.
