Reinforcement detailing of a slab is influenced by its support conditions. Slab is usually supported on walls or beams or columns.
Concrete surfaces, which bear extreme load due to heavy trucks or machinery, require concrete rebar reinforcement. Rebar reinforcement resists cracks in concrete which may occur because of tension forces. Rebar facilitates to prevent cracks from being expanded largely by controlling cracked slabs from moving apart.
- The objective of a slab is to cover spaces by means of roof or floor.
- Slab is laid on walls or beams or columns.
- Slab that is supported directly with columns are defined as flat slab.
