The paper presents the nonlinear section analysis for composite steel-concrete beams with different degrees of shear connection. The analysis is fiber based, i.e., integration over the cross section is performed numerically, and any uniaxial nonlinear material model can be assigned to the steel and concrete parts of the cross section or to the reinforcement bars. The analysis assumed full interaction between steel and concrete and therefore, is suitable for analysis of composite steel-concrete beam cross sections with nonductile shear connectors. Its accuracy is verified on few experimental results. The presented section analysis is used in the parameter study in order to evaluate different methods proposed by design codes for determining the bending moment resistance of composite cross sections with nonductile shear connectors and different degrees of shear connection. The following effects are considered: variation of concrete and steel material models, presence of slab reinforcement, and creep of concrete. Special attention is paid on two different constructional methods: propped and unpropped. The weaknesses of the simplified design method in determining bending moment resistance are identified and recommendations for practical design analysis are formulated.

“…The value of this parameter is below the Eurocode 4 limit (K<0.40) for all the specimens. However, it has been reported that if the shear connectors have a larger deformation capacity, a lower degree of shear connection can be used in composite beams [27,28]. In this study, the proposed shear connectors possess very large deformation capacities (see Table 1).…”

Cold-formed steel (CFS) construction is widely recognised as an important contributor to sustainability and green construction. Thus, the use of CFS construction is encouraged and had been advanced by innovations in its structural applications. One such innovation that has recently gained popularity is the use of CFS sections in composite construction. The researchers assembled two CFS Clipped channels back to back to construct Ibeam sections for testing. Innovative bracket shear connectors were also developed and inserted between concrete slabs and steel beams in order to provide composite action. The composite beams were drastically stronger and stiffer than non-composite beams. The experimental results were validated theoretically with a high level of correspondence. The proposed composite beams with CFS sections were found to be strong and stiff enough to be used in the construction industry.

“…In situ testing of a composite floor system with profiled deck was also carried out by Lloyd & Wright [18] in Cardiff. In addition to the above work on profiled decks with welded headed stud connectors, research on composite beams with profiled decks and non-welded shear connectors was carried out by Thomas & O'Leary[19] at Salford University in 1988 and Crisinel [20] at EPFL, Lausanne in 1990. Since the early 1990s, research on composite construction has moved towards connections and frame stability.…”
