Problem $2.$ A simply$-$supported slab bridge is to be designed based on the following parameters:

Length of bridge $=9m$

$fc{C}^{\text{'}}=28$MPa

$fy=415$MPa

Standard Loading: MS$18$ and Alternate Loading

Unit weight of concrete $=23\mathrm{.}6k\frac{N}{m}3$

Unit weight of $40-$mm asphalt $=19k\frac{N}{m}3$

Dead load due to sidewalk, railings, utilities, etc. $=6\mathrm{.}5$kPa

Effective slab depth $=hf-100mm$

Diameter of longitudinal bars $=36mm$

Diameter of transverse bars $=28mm$

Design the slab thickness and steel reinforcements then draw the cross$-$sectional detailing of the slab bridge.
