DOIAbstract
The resistance of steel-concrete composite trusses is significantly influenced by shear connection producing interaction between the steel beam and concrete slab. To create the interaction between these structural parts, it is needed to prevent the relative slip at the steel-concrete interface using the shear connectors. Push-out testing can reflect the more real effect of the longitudinal force and reproduce the distribution of the shear force between the steel section and concrete slab. The finite element analysis is used in the paper to investigate numerically this structural system behavior, exploiting finite element computer procedures
