One-Way & Two-Way Slabs

(1) One-Ways Slabs

Following are some of the important Factors and criteria regarding One-Way Slabs:

  • Length to Width ratio of the slab should be equal or more than 2 (L/W >= 2)
  • Load Transfer in One direction (in short direction)
  • Beams are provided in one direction (along the length)
  • Main-Bars are provide in short direction because it is the load carrying rebars while the Temperature/Distribution Bars is used in long direction to just cater the unwanted stresses due to temperature or shrinkage.

(2) Two-Way Slabs

Following are some of the important Factors and criteria regarding One-Way Slabs:

  • Length to Width ratio of the slab should be less than 2 (L/W < 2)
  • Load Transfer in both direction ( That’s why its called Two-Way Slab)
  • Beams are provided in both direction.
  • Main-Bars are provide in both direction because loads are transfer in both direction due to it geometry.
