SLAB REINFORCEMENT DETAIL
One way Slab – These types of slab are when twice the shorter span is less than the longer span, it is considered a one-way slab. It is called a one-way slab because it will bend in one direction only. (along a short span) The following figures represent the simple steps and rules for laying the reinforcement.
The figures below show the basic steps and rules for laying reinforcing bars in a one-way slab.
Two Way Slab – when twice the shorter span is greater than or equal to the longer span, it is called two way slab. Two way slab will carry load in both directions so the bending will be in both directions(two way bending) and the main reinforcements is provided in both directions.
The following figures are the simple steps and basic rules on how to lay reinforcing bars in a two-way slab.
Difference between One Way Slab and Two Way Slab
One Way Slab
Supported by the beams on the two opposite sides.
Main reinforcement is provided on shorter span due to bending
Main reinforcement is provided in only direction.
Loads are carried along one direction.
Two Way Slab
Supported by beams on all the four sides.
Main reinforcement is provided in both sides due to bending occurs on both sides
Main Reinforcement is provided along both the directions.
Loads are carried along both the directions.
