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 FEM based software in which the interface properties between materials can be modeled to a great level of detail. In the present study the influence 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. 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. Composite beams are also modeled to study the influence of cohesion and friction coefficient, and are compared with behavior of solid and non-composite beams
