4. One way slab is spanning in the shorter direction with main reinforcement and the distribution of reinforcement in the transverse direction.
In one-way slab, Main bars are provided in shorter direction (Cranked bars) and distribution bars are provided in Longer direction (Straight bars). Whereas in Two-way slab Main bars (cranked bars) are provided in both directions.
