What is the different between the one way slab and two way slab?
One Way Slab
one way slab is supported by beams on 2 sides of longer span (rectangular).
Two Way Slab
Two way slab is supported by beams on 4 sides of both span(square).
One way slab
In one way slab L/B>2 .here length is more than breadth
In one way slab the Main reinforcement should be provided on one direction.
The One way slab is supported by two parallel beams or walls.
In one way slab the Main bars Dia should be not less than 12 mm.
In one way slab the Distribution bars Dia should be not less than 8 mm.
Two way slab
In two way slab L/B<2 .here length and breadth are almost equal.
In two way slab the Main reinforcement should be provided on both direction.
The two way slab is supported by four parallel beams or walls.
Main bars Dia should be not less than 12 mm.
Distribution bars Dia should be not less than 8 mm.
Reinforcement of slab depends on size of room / slab.

Punching shear is a phenomenon that occurs in reinforced concrete slabs or footings when there is a concentrated load or reaction near a column or support, causing a shear failure. It typically happens when the load exceeds the capacity of the concrete to resist the shear forces, resulting in a failure mechanism resembling a cone-shaped "punching" through the slab.
****To prevent punching shear in current buildings or during the design stage, the following measures can be taken:
+ Adequate slab thickness: Design the slab with sufficient thickness to resist the anticipated punching shear forces. The required thickness can be determined based on structural analysis and design codes.
