DESIGN OF SLABS
.
✅ Aspect Ratio (Definition & Formula)
The aspect ratio (AR) is calculated using:
Aspect Ratio = Ly / Lx
- Ly = Longer span of the slab
- Lx = Shorter span of the slab
✅ Types of Slabs Based on Aspect Ratio
1. One-Way Slab
If Ly / Lx ≥ 2, the slab is classified as a one-way slab.
- Load is carried mainly in one direction
- Typically supported on two opposite sides
2. Two-Way Slab
If Ly / Lx < 2, the slab is classified as a two-way slab.
- Load is distributed in both directions
