Abstract : This research investigates the structural behavior of simply supported composite beams, in which a ferrocement slab is connected together with cold-formed steel (CFS) beam by means of shear connector. This system, called Precast Cold- Formed Steel-Ferrocement Composite Beam System, is designed to rely on composite action between the CFS sections and Ferrocement slab where shear forces between them are effectively transmitted via shear connector's enhancement. CFS sections have been recognized as an important contributor to structures in the developed countries, and a sustainable ‘green’ construction material for low rise residential and commercial buildings. However, it still remains as insufficient data and information on the behaviour and performance of CFS in composite construction in composite action is yet to be established. One limiting feature of CFS is the thinness of its section that makes it susceptible to torsional, distortional; lateral torsional, lateral distortional and local buckling. Hence, a reasonable solution is resorting composite construction of structural CFS section integrated with reinforced concrete deck slab. An efficient and innovative beam system of built-up CFS sections acting compositely with a concrete deck slab has been developed to provide an alternative composite system for floors and roofs in buildings. In this study, ferrocement is an alternative solution by providing concrete deck as a slab. Experimental tests comprised of a total of six full-scale simply supported composite beams with variable parameters were tested to failure. The main variables considered in the study are the shape of section (I and C as CFS beams), thickness (2, 3 and 4) of the CFS section and number of layers of wire meshes (2, 4 and 6 layers). Four points load bending system was used to test the specimens.
