- Composite Steel-Concrete construction is widely used in buildings and bridges even in regions of high seismic risk. It is now common practice to use cold formed steel sheets as permanent formwork for the support of the soffits of reinforced concrete and also as part of the tension steel in the composite beam that is formed after the concrete has hardened. The construction should ensure monolithic action between the prefabricated steel and in-situ concrete so that they act as a single structural unit. Structural elements, such as anchors, studs, channels and spirals, intended to transmit the horizontal shear between the prefabricated member and the cast-in-situ concrete and also to prevent vertical separation at the interface. Shear connectors, anchors (hoops, loops, and struts) are used as a means for comprising steel and concrete, as well as friction through high value crews and their combination. There is a common term – Shear connectors that defines the various forms of steel structural parts connected to the upper segment of the steel plate most often by welding. In this experimental analysis the T-shape shear connectors will be used in composite beams as they have the highest characteristic resistance and the mode of failure changes for different concrete strengths and different arrangements. Moreover the shear connectors will be provided in various arrangements and the optimum location which gives the high flexural and shear strength going to be arrived. The flexural strength between conventional reinforced concrete beam and composite beams with shear connector is were compared and found that the T-Connectors facing the centre of beam (NT-2) holds the cold formed steel well with the concrete compared to other composite beams
