Basic Layout Sketch:

Draw a basic layout of a ribbed slab with hollow blocks. Indicate the

positions of the ribs and the hollow blocks.

Label the main components such as ribs, hollow blocks, and the slab

topping.

Reinforcement in Ribs:

Sketch the reinforcement details within a single rib. Show the main

reinforcement bars and any shear reinforcement $($stirrups$).$

Indicate the spacing and size of the reinforcement bars.

Top and Bottom Reinforcement:

Draw a cross$-$section of the ribbed slab showing the top and bottom

reinforcement.

Label the main reinforcement bars, distribution bars, and any additiona

reinforcement required for specific load conditions.

Reinforcement at Supports:

Sketch the reinforcement detailing at the supports $($e$.$g$.,$ beams or walls

Show how the reinforcement bars are anchored and overlapped.

Indicate any additional reinforcement required at the supports to handle

shear forces.
