Abstract: Concrete is one of the most widely used construction material in the construction industry throughout the globe. Many scientists and researchers are looking for a supplementary construction material that is eco-friendly and can contribute toward sustainable development. Composite sections which are made of concrete and cold formed steel sheets are extensively used in foreign countries to attain more structural proficiency. The structural strengthening of composite beams manufactured with Self compacting concrete and cold formed steel members are discussed in this article. CFS sheets of 2mm have been used to reduce the self-weight, thereby including additional tension reinforcement of 12mm diameter, which can take heavy loads and improve the structural efficacy. Cold formed steel sheets are used as trapezium shaped perforated sections for composite beam. The behavior of composite SCC beams raises the ultimate load carrying capacity and drops the ultimate mid span deflection for increasing the load and reducing the flexural crack widths, compared with control beam.
