Composite action of two concrete members is achieved by the interface shear transfer between the two members, this mechanism is of great significance. The interface shear carrying capacity is dependent on the surface properties and shear connectors provided. In the current research ATENA is used, it is a FEM based software in which the interface properties between materials can be modeled to a great level of detail. In the present study the effect of angle of inclination, size and the depth of embedment of truss connector on the load carrying behavior is studied with the help of a beam model. Based on the results of the beam study shear connectors are then used in a one way slab of size 1m X 1m in varying patterns and the flexural load carrying capacity is compared with that of a solid slab and a non-composite slab. The angles of inclination varied are 30o, 45o, 60o and 75o with varying bar diameters of 8mm, 10mm and 12mm. Angles between 60o to 75o are found most efficient with no significant changes when diameters are varied. The ultimate load for a given connector is found to be independent of the depth of embedment. 8mm truss connector with 60o inclination and 70mm depth of embedment is used as shear connectors in a square one way slab in varying configurations and analyzed for pure bending. It is found that the load carryingcapacity of the slab increases as the number of shear connectors in the longitudinal direction increases and shearconnectors when provided in the transverse direction has negligible effect.
