For the $4-$story building with the plan shown above, girders are along axes $3,5,B,$ and $C,$ beams are along axes $2,4,$ and $6,$ and spandrel beams are the beams on the edges.

The first story height is $5m.$

Other story height is $3\mathrm{.}5m($top of slab to top of slab$)$

Column dimensions $=5050cm$

Spandrel beams: $3055cm$

Interior beams: $2550cm$

Girders: $6070cm$

Select slab thickness based on the deflection limits requirement of ACI $318-19$ to the nearest centimeter.

Floor service live load $=3\mathrm{.}5k\frac{N}{m^2}$

Floor service dead load $=2\mathrm{.}5k\frac{N}{m^2}$
