Paper Title
Analysis and Designing Structure of Prestressed Concrete Slab (Flat Slab)

Abstract
Beam less floor directly resting on support (column and/ wall) is known as flat slab. Because of this, Story height can be maintained uniform throughout. This provides us an ease of installation of mechanic and electric services. This also helps us in reducing the cost of formwork. Flat slab reduces the loads on foundation because of less height of structure. It gives us plain ceiling which gives an attractive appearance. Flat slabs are subjected to gravity and lateral loads. Gravity load analysis of flat slab is carried out by Direct Design Method (DDM) and Equivalent Frame Method (EFM) as prescribed by different standards. On site some times because of site conditions or the owners requirements the column orientation may not get in an alignment this is known as staggered column conditions. In those conditions we have to use Equivalent Frame Method for analysis and design of flat slab. Keywords - Prestressed Concrete Slab , Strength of Slab .
