It can be classified in different ways: TYPE OF FLOOR SYSTEMS It can be classified in different ways: By Material Used By Structural action of the slab By Method of construction

By Material Used Floor slab : Reinforced concrete, Timber, steel, brick Beam or Girder : Reinforced concrete, Timber, steel

By Structural action of the slab Bearing slab (Slab on ground) One way slab Two way slab Joist slab, Waffle slab Flat Slab Irregular slab

By Method of construction Cast in situ concrete Slab and Beam Precast concrete slab….on Beam… Precast beam and slab Precast slab on steel beam

Factors for Design and Cons. Load… LL., DL., FL. Span Thickness Deflection and Vibration Stiffness Methods….
