Suspended slabs

Diagram of a three-storey building with a basement. The basement has a ground slab. There are floor slabs between first floor and second floor, and in between half of the second floor and third floor. The other half of the second and third floor has a balcony slab. At the top of the building is a roof slab. Suspended slabs are slabs that are not in direct contact with the ground. They form roofs or floors above ground level.

Suspended slabs are grouped into two types:

  • one way slabs which are supported on two sides
  • two way slabs which are supported on all four sides.

The way a slab spans its supports has a direct impact on the way in which the slab will bend.
