Abstract: Cold formed construction has widely recognized as an important contribution of saving in weight of steel as well as it can be formed according to strength requirements. Cold formed sections may have higher moment of inertia as compare to same weight hot rolled sections. Composite construction is usually associated with hot rolled sections especially I section, double C channel section considering high strength to weight ratio. The traditional hot rolled sections can be replaced by high strength cold formed sections considering its strength properties, less weight, easy fabrication and to fit demands of optimized design. This paper deals with experimental study of flexural behavior of composite beam using hot rolled as well as cold formed steel section. Two composite beams were casted using hot rolled ISMC 100 (back to back with spacing 50 mm) and Cold formed lipped channel section (back to back with spacing 50 mm). Experimental study conducted with simply supported loading conditions under two-point loading. Cold formed lipped channel section is pre- fabricated considering cold formed sectional properties given by EN 1993-1-3. Loading is given with load increment of 50 kN. Values of mid span deflection and slip at interface were recorded. The test strength of composite beam compared with design strength predicted by Eurocode standard.
