In developing countries like India, the use of post-tensioning method due to its various Applications has been increasing day by day. Also, the Post-tension flat slab construction has long been popular for medium to high rise building such as office buildings, hospitals, Residential buildings, university, and parking buildings. In the present study, a commercial office building has been selected to perform a parametric study. Various slab system i.e. Flat slab with RC beam, RC slab with RC beam, Post tensioning flat slab with drop panel and Post tensioning flat slab without drop panel with Post-tensioning voided flat slab have been studied to compare their performance by applying Time History Analysis. Various parameters,such as thickness of slab, grade of concrete, punching shear, column size etc. have been selected for the present study to arrive at the best suitable slab system By using these voided systems, it is possible to lighten the weight of slabs as much as 35%. “A 21-inch-thick slab can be reduced by the equivalent of 4 to 5 inches in thickness of concrete or 30 to 40 pounds per square foot of dead load,” as concluded by a research. A typical slab with 40-foot spans is 16 inches thick, but a voided slab with these spans can reduce the equivalent solid thickness to about 12 inches. This reduced weight of building floors also permits engineers to reduce columns, walls, and foundations as much as 40%, although concrete can’t be removed from all locations in a floor slab; voids are omitted near columns to maintain slab punching-shear capacity
