The focus of the study was on the numerical analysis of the model of the beam integrated with the innovative shape of connector in the form of the cut-out web. The model can be used as an integrated binding joist or bridge girder. This type of connector was a specifically shaped part of the web of the steel section. The first part of the study was focused on the analytical design of the integrated beam. A hot-rolled crosssection was chosen from the half of the hot-rolled HEB section. The second part of the study was modelling of the inte-grated beam. Beam geometry, load and boundary conditions were used as in the first part of the study. ADINA software, based on the finite elements method, was used for numerical analysis. The HEB steel section and the reinforced concrete slab were modelled by means of 3D Solid elements, whereas the reinforcement bars were modelled using truss type ele-ments. The stresses and strain in the steel and concrete elements, distribution of forces in reinforcement bars and concrete cracking were evaluated.
