One-way slab: Design of one way RCC slab is similar to design of beam but the only difference is during the design of one way slab we take unit width of slab as a beam width. Slabs are designed for bending and deflection and not designed for shear. Slabs have much small depth than beams. Most of slabs subjected to uniformly distributed loads. Note: In one way slab, the maximum bending moment at a support next to end support.
