[en] In the last years, new connectors of steel-concrete composite flooring systems have been developed and investigated to enhance the circularity and standardisation of building components. Recent studies showed that timber can be used as an alternative to the concrete slab in hybrid structures. However, the knowledge in steel-timber composite flooring systems is still very limited. This contribution presents numerical investigations of steel-LVL timber composite beams. The load deformation behaviour was determined through 3D finite element models. The design resistance of the composite beams was estimated analytically through a strain-controlled approach. The results of this study show that the resistances obtained in the numerical models and the strain-controlled approach are in good agreement. Moreover, obtained deflections and slip values were given at ultimate load.
