WebMay 21, 2024 · Based on the length and breadth of Conventional Slab is classified into two types: One-Way Slab Two-Way Slab 1. One Way Slab: One way slab is supported by beams on the two opposite sides to carry the load along one direction. The ratio of longer span (l) to shorter span (b) is equal or greater than 2, considered as One-way slab.
