A constructive and technological solution is proposed for a steel-reinforced concrete I-beam with a reinforced concrete top flange and a steel T-element with a perforated wall. The fundamental differences of this design are described. The paper proposes a numerical simulation of the stress-strain state both in the elastic formulation and taking into account physical nonlinearity. The developed constructive solution allows achieving significant savings in material costs both in new construction and during reconstruction.
