Abstract
The paper proposed a numerical model of a shear connection between a reinforced concrete slab and a steel shape. The connection was made using a top-hat profile. A method for conducting experimental research on shear connections in the composite structures was presented. Geometric dimensions and material parameters of the analysed model of connection, on which the experimental research was conducted, were noted. The results of the conducted experimental research were compared to the results of the numerical analysis performed using ANSYS software. displecement curves were analysed for both cases and any correlation between experimental and numerical results was noted.

Increase in usage of steel-concrete composite floors in frame buildings causes perfecting of the existing and development of new constructional solutions [1]
On the basis of the calculations made, it was determined that the greatest general deformation for the maximum shearing force equal to 320 kN occurs in the sheet, on the edge of the composite slab, at the contact point of the concrete slab, and equals 15,46 mm (Fig. 6)
The maximum deformation of powder-actuated fasteners connecting the profile to the HEA 160 section equalled 3,55 mm, and deformation of the top-hat profile equalled 4,41 mm
Summary
Increase in usage of steel-concrete composite floors in frame buildings causes perfecting of the existing and development of new constructional solutions [1]. One of the most effective constructions of this type is a floor in which a rolled steel section (most frequently I-section) is connected with a concrete slab made
