Q$1)$ The given Figures show plan view for architectural project. All beams have the same width and thickness. Design the slab $($S$3$ only$)$

Determine slab thickness for all the slabs, and calculate the area of main steel in the slab $($slab $3$ only$),$ then determine the required spacing between bars. Find the Shrinkage steel, use $10).)=3k\frac{N}{m^2},LL=(4k\frac{N}{m^2}.$ The concrete compressive strength, $f^{\text{'}}c=30$MPa and the reinforcing steel yield strength, fy $=420$MPa
