What is the difference between a one-way slab and a two-way slab in terms of design and load distribution?

Question

Accepted Answer

One-way slabs distribute load primarily in one direction, while two-way slabs distribute load in two directions.

One-way slabs are designed to span in only one direction, typically supported on two opposite sides. They distribute load primarily in one direction.
Two-way slabs are designed to span in two directions, supported on all four sides. They distribute load in both directions, providing more balanced load distribution.
One-way slabs are more economical for smaller spans and lighter loads, while two-way slabs are more suitable for larger spans and heavier loads.
In terms of reinforcement, one-way slabs typically have reinforcement bars running in one direction only, while two-way slabs have reinforcement bars running in both directions for better load distribution.
Examples of one-way slabs include slabs supported on beams, while examples of two-way slabs include flat slabs and waffle slabs.
