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”
