TYPE OF FLOOR SYSTEMS


It can be classified in
different ways:


By Material Used


By Structural action of the
slab


By Method of construction


19

By Material Used


Floor slab : Reinforced
concrete, Timber, steel, brick


Beam or Girder : Reinforced
concrete, Timber, steel

20

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

21

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
