“…Tsalkatidis and Avdelas (2010) employed the use of nonmonotone material laws for the interface shear bond interaction, treating it as a two dimensional contact model, in modeling a simply supported one-span composite slab. In similar modeling representation, Tzaros et al (2010) used a nonconvex-nonsmooth optimization technique for the mechanical description of the shear bonding. More recently, Chen and Shi (2011) presented a universal FE model for composite slabs, in which the shear bond interaction was modeled as a contact element incorporating both adhesion and friction, employing the Coulomb friction model, and considering both geometrical and material nonlinearities.…”

Eurocode 4 design provisions specify two methods for the design of composite slabs, namely the m-k and the partial shear connection (PSC) methods. Currently, the m-k method includes the concrete thickness and the shear span of the slab as variables while the PSC method does not. This has resulted in a better accuracy for the m-k method when slabs with varying dimensions are considered. It is demonstrated in this paper that the horizontal shear bond stress varies with the ratio of shear span to effective depth of slab, defined as the slenderness. To include such an effect, a linear shear bond-slenderness equation is proposed. Using the proposed relationship, a linear interpolation of shear bond strength based on two configurations, determined from the outcomes of the bending tests for compact and slender slabs, has been satisfactorily performed. The shear bond strength obtained from this interpolation can be used in collaboration with the existing PSC method, such that the accuracy of the prediction of the composite slab capacity can be considerably improved, the validity of which has been verified with published results from literatures.

“…Work published by Abdullah and Easterling [20] developed a force equilibrium method to calculate the horizontal shear force-slip relationship in the FE modeling of composite slabs. Tzaros et al [21] applied nonconvex-nonsmooth optimization to simulate the flexural behavior of composite slabs. Nevertheless, these macro-level element models present some obstacles to the precise simulation of the latticed girder and the contact between the precast and cast-in-place concrete.…”

In this study, on-site bending experiments which represented realistic and pragmatic engineering applications were performed to investigate the resistance, deflection, and cracking process of latticed girder composite slabs. Then, utilizing ABAQUS software, nonlinear finite element (FE) models were established to investigate the behavior of the slabs. The modeling took into account the contact between the precast and cast-in-place concrete interfaces. Additionally, a damage-cracking methodology was introduced to evaluate the crack opening width of the slab. The results demonstrated that the proposed numerical model was capable of reproducing the typical behavior of the composite slabs’ performance analysis. The experimental and numerical results demonstrate that the lattice girder composite slabs conformed to the requirement of existing design codes.

“…Interface actions between the steel deck and the concrete of a composite slab were treated as a unilateral contact problem by Tsalkatidis and Avdelas (2010) and Tzaros et al (2010). In order to achieve composite action at the interface between the profiled steel deck and the concrete, Chen and Shi (2011) developed a 3D contact analysis model in which a deformable interface was adopted rather than a rigid interface between the two contact bodies.…”

A finite-element model is proposed to simulate the load behaviour of composite slabs with studs as end anchorages.The model is verified against physical tests on 36 composite slabs with varying thickness of steel deck, diameter and height of the studs, concrete strength and length of shear span. The longitudinal shear strength contributed by the end anchorage is evaluated and compared with the design shear strength of individual studs proposed in different design codes. The contribution of studs as end anchorages to the shear-bond strength of composite slabs is found to be substantial and should be considered in design assessments. A tentative design method to evaluate the strength of composite slabs with end-anchorage studs is proposed.
