“…The most popular structural solution of the steel-concrete composite beams are beams with slabs concreted on profiled steel sheets. The sheet metal, apart from cooperating with concrete in the use phase of the slab, is also a working platform and formwork lost in the execution phase [1][2][3]. From a structural point of view, the slab serves as reinforcement for positive bending moments.…”

The paper presents an analysis of the innovative connector for manufacturing a steel–concrete composite beam. The connector consists of a corrugated metal sheet in the shape of a dovetail and shot nails. The nails are shot through the sheet fold into the flange of the steel I-section. Experimental studies of push-out tests were carried out. The conducted tests proved that the proposed solution can be applied as the fastener for steel–concrete composite beams for the construction of ceilings in utility public buildings with small beam’s span. Considering the criteria presented in the Eurocode 4 standard and the results of the experiments, it was proven that all analyzed types of fasteners are ductile. The connector made of sheet with a thickness of 1.00 mm and 2 nails is characterized by a breaking load of 30.83 kN. The load-bearing capacity of the fastener can be adjusted by changing the corrugated sheet thickness and changing the number of nails shot in the single fold of the sheet.

“…Plastic deformations in the connection occur under the action of large shear forces and result in a reduction in connection stiffness. Therefore, stiffness of the connection between the concrete and profiled steel sheeting shall be taken into account in the determination of the stiffness of composite slabs, as has been indicated in investigations by many authors [11][12][13]. In Eurocode [14] for the design of composite structures, it is pointed out that, in the design of composite slabs, yield of the connection between concrete and profiled sheeting can be taken into account.…”

“…This variation is characterized by the stiffness of connections between the concrete and the steel beam which in accordance with EC 4 is defined by the degree of shear connection h. Stiffness and the strength shear of the connection depend on multiple factors. Investigations show (Faggiano et al 2009;Gurkšnys et al 2005;Jurkiewiez et al 2011;Jurkiewiez, Braymand 2007;Motak, Machacek 2004;Smith, Couchman 2010) that it is not always possible and necessary to reach the absolute shear connection or to avoid the slip between the layers. The same resistance is achieved by increasing the cross-sections of the layers and decreasing the connection stiffness.…”

The composite steel and concrete structures are used for constructing bridge floors and others buildings. The joint action of composite structures as well as their economic efficiency depends on the connection between the layers, i.e. stiffness of the steel beam and the concrete slab. Under the effect of external load in the connection of steel and concrete the shear deformations occur. The size of these deformations depends on the effective shear stiffness of the connection of layers. When designing the composite steel and concrete structures it is very important to accurately calculate their deflections. Deflection is largely dependent on the stiffness of the connection of steel and concrete. In isolated cases it is purposive to calculate the necessary stiffness of the connection of steel and concrete taking into consideration the permissible deflection of the composite steel and concrete structure. This paper gives the methodology which, based on the known permissible deflection of the structure, allows to calculate the necessary equivalent effective shear modulus of the steel-concrete connection. Experimental investigations of the composite steel and concrete beams were carried out. Deflections of the composite beams, also the shear deformations of steel and concrete connections and the effective shear stiffness of this connection were determined. Theoretical calculations of the effective shear stiffness of the connection of concrete slab and steel beam of the experimental composite steel and concrete beams were conducted. Investigations showed a rather good correspondence between the experimental and theoretical investigation results.
