“…With the carefully selected stressstrain curves for both reinforced concrete flanges and steel sections, it was demonstrated that these finite element models were able to predict the structural behaviour of the composite frames conservatively. A three-dimensional (3-D) finite element model was proposed by Ahmed and Nethercot (1996) to assess the effects of shear and axial forces on the load carrying capacities of composite end-plate connections. Shell elements were used to model the steel beams and the steel columns as well as the end-plates.…”

A three-dimensional (3-D) finite element model is established to predict the structural behaviour of composite end-plate connections with full incorporation of material and geometrical nonlinearities. A two-dimensional (2-D) finite element model is also proposed as a tool for a comprehensive parametric study, analysis, and design. The accuracy of both the models is verified by comparing the numerical results with those from tests and a design model. Various important structural behaviours of composite end-plate connection are also studied through the numerical and analytical simulations. These models are regarded as effective tools for conducting performance-based design of composite connections and semicontinuous beams with reasonable consideration of nonlinear deformation characteristics of both tensile reinforcements and shear connectors. Résumé : Un modèle tridimensionnel par éléments finis est établi pour prédire le comportement structural des plaques d'extrémité composites avec pleine incorporation des matériaux et des non linéarités géométriques. Un modèle bidimensionnel par éléments finis est également proposé comme outil d'une étude paramétrique, une analyse et une conception complètes. La précision des deux modèles est vérifiée en comparant les résultats numériques à ceux d'essais et du modèle de conception. Divers comportements structuraux importants des plaques d'extrémité composites sont également examinés par simulation numérique et analytique. Ces modèles sont considérés des outils efficaces pour des conceptions basées sur le rendement des poutres à connexions composites et semi-continues en tenant compte, raisonnablement, de caractéristi-ques de déformation non linéaire des armatures tendues et des connecteurs.Mots-clés : connexions composites, modélisation par éléments finis, modèle de conception, connecteur, conception basée sur le rendement.

“…In addition, the first eigen-mode is adopted as the initial imperfection in the nonlinear analyses, and the magnitude of the maximum initial imperfection is taken as 25% of the web thicknesses of the steel beams (Ahmed and Nethercot 1996). Figure 5a illustrates a typical initial imperfection.…”

“…It was found that the contribution from the reinforcement and shear connectors was the most significant. Ahmed and Nethercot [2,3] extended the work to investigate the effects of high shear to moment ratio and the presence of column axial load on the behaviour of the composite joints.…”
