Introduction Basic definition of flat slab: In general normal frame construction utilizes columns, slabs & Beams. However it may be possible to undertake construction with out providing beams, in Such a case the frame system would consist of slab and column without beams. These types of Slabs are called flat slab, since their behavior resembles the bending of flat plates. Components of flat slabs: Drops: To resist the punching shear which is predominant at the contact of slab and column Support, the drop dimension should not be less than one -third of panel length in that Direction. Column heads: Certain amount of negative moment is transferred from the slab to the column at he support.
To resist this negative moment the area at the support needs to be increased .this is facilitated by providing column capital/heads Flat slab with drop panel & column head 6
