$(12)($i$)6500mm=66\mathrm{.}000mm$

$L_{300mm}$

ine two$-$way slab is without interior beams between supports. This example designs the internal strip along grid line B$.$ Lateral loads are resisted by shear walls; therefore, the design is for gravity loads only. uniform loads:

Concrete density including reinforcement at $23\mathrm{.}5k\frac{N}{m^3}$

Superimposed dead load $D=0\mathrm{.}75k\frac{N}{m^2}$

Live load $L=4\mathrm{.}8k\frac{N}{m^2}$

Material properties:

$f_c^{\text{'}}=35$MPa

$f_y=420$MPa

Check if the two$-$way slab could be designed using direct design method $($DDM$).$

Determine the slab thickness for the interior panels.

Define the geometry of the panels and the strips.

Calculate the total panel moment.
