Design continuous one$-$way slab system shown and draw the reinforcement bars on the slab system

following the provisions of TS$500.$ Select half straight and half bent$-$up bars. The slab carries

characteristic dead load of $2\mathrm{.}5k\frac{N}{m^2}($excluding self$-$weight$)$ of coating, leveling concrete and ceiling

plaster. Live load $=2\mathrm{.}0k\frac{N}{m^2},$

The construction materials considered for the concrete consist of Grade C$25,$ whereas, for steel

reinforcement consist of Grade S$420.$ The unit weight of concrete must be taken as $25k\frac{N}{m^3}.$

Design Load: $(P_d=1\mathrm{.}4G+1\mathrm{.}6Q)$

Use: Diameter of reinforcement $=10mm(100p.)$

Span moments:

$\frac{1}{11}{P}_d{L}^2$

Support moments$(External)$:

$\frac{1}{24}{P}_d{L}^2$

Support moments$(Internal)$:

$\frac{1}{8}{P}_d{L}^2$
