“…Concrete cracking may occur simultaneously with slip in a form of macrocracks from bending and microcracks around embossments; similarly as around a reinforcing bar in reinforced concrete [2]. Microcracks can result in abrasion around embossments edges or local concrete peeling when the embossments are close to each other [3]. The number of factors influencing the bearing capacity makes it difficult to describe slab behaviour analytically.…”

The load bearing capacity of steel and concrete composite slabs using thin-walled steel sheeting with prepressed embossments is in most cases determined by its resistance in longitudinal shear. The designing of composite slabs still requires the performance of full-scale laboratory bending tests. Small-scale shear tests cannot include all of the influences affecting the bended slab but using an appropriate procedure the shear characteristics obtained from them can be used for determining the bending capacity of the slab. Two such procedures are compared in this paper.End constraints effectively increase the load bearing capacity of the composite slabs. Two different types of easily assembled additional end constraints are also tested and compared in this paper. Small-scale tests are used to obtain their shear bearing characteristics and to predict the load bearing capacity of bended slabs using these constraints.

“…Failure can occur via the local buckling of the steel sheet, the deformation of the dimples, the peeling off of concrete, the crumbling of concrete, etc. It is therefore complicated to describe the shear behaviour in a general manner [3]. Failure modes in composite slab behaviour [1].…”

Composite structures fabricated from thin-walled steel sheeting and concrete slabs are especially suitable for roof and floor bearing structures. Using embossments for the shear connection between the sheeting and the concrete simplifies and accelerates the construction process because it ensures the composite action of the two materials without any need for additional reinforcement. This article is focused on this type of connection. It contains a short review of thin-walled sheeting manufactured in Western Europe and presents results obtained from the experimental testing of specimens. These specimens were tested by vacuum loading and by cyclic loading in four-point bending tests. Small scale specimen tests were performed to determine the shear behaviour and to adjust numerical models.

“…The local failure of the interface interlock originates from two components: (1) steel yielding and (2) local crushing of concrete around embossment ends that has a softening effect on the embossments' effective geometry [11]. Accordingly, those two phenomena are needed to follow by the numerical model to get correct prediction for the embossment's behaviour.…”

“…The coefficient of friction is a scattered physical magnitude [11]. It characterizes the quality of the contact surfaces, and it is affected by a large number of uncontrolled factors like cement type, dosing of concrete, type and size of aggregates, setting up and curing processes, moisture level, etc.…”

The subject of the ongoing research work is to analyze the composite action of the structural elements of composite floors by experimental and numerical studies with a special focus on the rolled embossments on the steel surface. The mechanical and frictional interlocks result in a complex behaviour and failure under horizontal shear. This is why the design characteristics can be determined only by standardized experiments. The aim of the current research is to determine the longitudinal shear resistance for composite floors, by applying advanced numerical model. The paper has a focus on the basic numerical models with particular considerations on the concrete model and on the numerical model of rolled embossments.Keywords composite floor · rolled embossment · concrete damage · numerical modelling · ANSYS Acknowledgement This work is connected to the scientific program of the "Development of quality-oriented and harmonized R+D+I strategy and functional model at BME" project.
