Answer the following question:

The Figure below shows plan for floor system consists of solid slab and supported beams. The interior beam width $b=300mm$ and the slab thickness $t=110mm.$ The finishing load on the slab $FL=3\mathrm{.}0k\frac{N}{m^2}$ and the live load on the slab $LL=2\mathrm{.}0k\frac{N}{m^2}$

Given: $,f^{\text{'}}=28$MPa,$f_y=420$MPa, Concrete cover $=40mm$

Stirrup dimeter, $\frac{O}{{?}_{}}10mm,$ Reinforcement bar diameter, $\frac{O}{{?}_{}}18mm$

Width of beams: $300mm,$ Columns dimension: $300**300mm$

Required:

$1$ Design the interior beam for positive and negative moments using reinforcement bar diameter, $\frac{O}{{?}_{}^{.}}18mm.$ Draw beam sections showing all dimensions and reinforcement details.

$2$ Design the interior beam for shear using stirrup dimeter, $\frac{O}{{?}_{}}10mm.$ Arrange the stirrups along the beam span and draw the shear reinforcement details.

$3$ Locate the theoretical cutoff points and establish the length of all bars at the positive and negative moment regions. Illustrated sketch is needed.

$4$ Verify all the ACI code requirement to control the deflection and cracks.

$5$ Design the slab

$4$ Design column C$1$ and C$2$
