[en] Slim-floor or shallow floor construction is characterized by the integration of a steel beam into a slab. The activation of a composite action between the steel section and the concrete slab leads to a significant increase of the bending capacity and the stiffness of the beam, allowing for larger beam spans. This
paper presents a fundamentally new method for assessing the load-bearing capacity of CoSFB-Dowels, which ensures a composite action of a composite slim-floor beam (CoSFB). Based on detailed analysis of push-out tests, extensive numerical simulations were performed in order to identify the contribution of
various parameters on the load-bearing capacity. Finally, an analytical formulation of the load-bearing capacity is presented, which has been derived by applying a simple second order plasticity approach.
