Two-way slab: If the proportion of long span to short span is under 2, then the slab is called a slab that stretches in two directions or a two-way slab.
The two-way slab design process
1- Select layout and type of slab. The type of slab is greatly influenced by architectural and construction considerations.
2- Select slab thickness to manage deflection. Also, examine if the thickness is sufficient for shear.
3- Opt for the design method.
Equivalent frame method- Apply elastic frame analysis to calculate positive and negative moments.
