Abstract

The design of structures for buildings and bridges is mainly concerned with the provision and support of load-bearing horizontal surfaces. These floors or decks are usually made of reinforced concrete as it satisfies the criteria of low cost, high strength, and resistance to corrosion, abrasion, and fire. Moreover the beams are also of concrete, so the monolithic nature of the construction makes it possible for a substantial breadth of slab to act as the top flange of the beam that supports it. At large spans and particularly where the susceptibility of steel to damage by fire is not a problem, for example in bridges and multi-storey car parks, steel beam becomes cheaper than concrete beam. By development of shear connectors, it is practicable to connect the slab to the beam so as to obtain the Tbeam action as in concrete construction. Composite construction has proven popular because it combines structural efficiency with speed of construction to offer an economic solution for a wide range of building types. Composite slab consist of profiled steel decking with an in-situ reinforced concrete topping. The decking not only acts as a permanent formwork to the concrete, but also provides sufficient shear bond with the concrete. So, when the concrete has gained strength, the two materials act together compositely. The composite interaction is achieved by the attachment of shear connectors to the top flange of the beam. Composite slab is commonly used (with steel beams & columns) in the commercial, industrial, leisure, health and residential building sectors. Although most commonly used on steel framed buildings, composite slabs may also be supported off masonry or concrete components. Above this, it has many beneficiary aspects like speedy construction, structural stability, shallower construction, sustainability etc. Here, our aim is to study development of program of the design of R.C.C. & Composite slab along with its parametric study. Programming is carried out using powerful MS Excel for design of slabs. Estimation of material quantity and cost are also studied here.
