Abstract

The aim of project is to check the cost effectiveness of Post-Tensioning Slab with other design methods. For that purpose multipurpose hall is chosen with the footprint of 6 x 8 m having the total slab area is (768 sq. m). The analysis done by hand calculation and using the following methods: 1) Flat Plate (Without Drop and capital ) and Post-Tensioning Slab by using equivalent frame methods 2) Flat slab with Drop and capital by using Direct Design methods and 3) Grid Slab by using IS code Methods. It is also an analysis by using M 35 and Fe 415 grade of concrete and steel. After designing the slab thickness of slab, total dead load, moments, shear stress and over all construction cost are compared. It concludes that construction cost of grid slab is more economical than other three methods for particular span of slab.
