Types of Solid RCC Slab
RCC solid slabs are three types depending on design criteria.
- One-way slab
- Two-way slab
- Cantilever slab
One-way slab – When can we called a solid slab one-way slab? If a solid RCC slab meets the following criteria then we can call that one-way slab –
The slab rests on two beams only,
The slab can be rested on four beams but the long-span of slab should be greater than two times of short-span. See the image below “One Way Slab”.
In one way slab, the main reinforcement should be along slab’s short direction.
Two-way slab – When a Solid RCC slab rests on four beams but long-span of slab is less than or equal to two times of short-span then we can call that slab a “two-way slab”. See Image below “Two-Way Slab”. In two-way slab, main reinforcement runs both in short and long direction and stay perpendicularly with one another.
Cantilever slab – Cantilever Slab has only one support at one end and other three ends are open. See the image below “Cantilever slab”. The main reinforcement of cantilever slab should be extended one and half times beyond its support.
