Analysis of Flat Slab
A flat slab is a reinforced concrete slab supported directly by concrete
VARIOUS TYPES OF SLABS
CHOICE OF TYPE OF SLAB FLOOR
The choice of type of slab for a particular floor depends on many factors. Economy of construction is obviously an important consideration, but this is a qualitative argument until specific cases are d
