Question $2(20$ marks$)$

Calculate the area of reinforeement required for the internal support at the shorter span for a slab panel with the dimension $4m6\frac{m}{c}.$ The slab panel is supported on Four sides, and it is continuous on two adjacent sides and discontinuous on the other two adjacent sides. The nominal$-$imposed live load is $2\mathrm{.}5k\frac{N}{m^2}$ and allow for floor finishes of $1\mathrm{.}5k\frac{N}{m^2}.$ Use the folowing parameters:

Fcu$=25MPG$ and $Fy=2\mathrm{.}50MPG$

Thickness of $S19b=170mm$

Cover $=20mm$

Density of concrete $=24k\frac{N}{m^2}$

Available reinforcement $y_{16}$ and $y_{10}$
