An experimental study was conducted to investigate the shear-bond behavior of composite slabs and to analyze Eurocode requirements on the longitudinal shear strength of composite slabs. The m–k and partial shear connection methods were analyzed. Two different types of profiled steel sheeting with up to three different thicknesses were considered. The experimental determination of these parameters must satisfy some requirements established in the Eurocode. These requirements penalize experimental results, so they can be very conservative in some cases. The present study explored the influence of such requirements on the estimated longitudinal shear carrying capacity and provided results that lead to a better understanding of the shear-bond behavior of composite slabs. This involved testing 30 composite slabs with different experimental requirements. The study assessed the influence of the previous cyclic load and the placement of crack inducers on the longitudinal shear strength. Moreover, bending tests of composite slabs with different steel sheet thicknesses were performed. Therefore, the study also analyzed the influence of steel sheet thickness on longitudinal shear strength estimated according to Eurocode 4 methods. Based on these results, the paper discusses the suitability of the experimental requirements applied to the profiled composite slabs tested.
► 30 composite slab specimens were tested with different set-up configurations. ► The shear-bond behavior of composite slabs according to Eurocode was analyzed. ► The suitability of the placement of crack inducers was assessed. ► The previous cyclic loading could be unnecessary for trapezoidal ductile profiles. ► The partial shear connection method was more suitable for different deck thicknesses.
