This paper present the displacement-based finite element formulation for the non-linear analysis of composite steel-concrete beams with partial interaction that occurs due to deformation of shear connectors. The formuation considers the non-linear behaviour of materials as well as shear connectors. The finite element for composite beams which is based on Newmark kinematical model has 8 DOF. Numerical applications are perfomed for simply supported beam and continuous beams. The results are compared with experimental data in order to validate the reliability of the formulation. The results are also disscussed for influence of partial interaction and non-linear behaviour of materials as well as shear connectors on behaviour of composite beams.

Background: In this work the behaviour of continuous steel-concrete composite beams with different shear connection distributions obtained from two design methods, i.e. Eurocode 4 and a proposed alternative approach, is analysed. Objective: For this purpose a finite element model specifically developed for the nonlinear analysis of steel-concrete composite beams is adopted. This finite element model includes material nonlinearity of slab concrete, reinforcement steel, beam steel as well as slab-beam nonlinear partial interaction due to the deformable shear connection. The inclusion of the partial interaction in the composite beam model provides information on the slab-beam interface slip and shear force and enables to model the failure of the shear connectors. Results and Conclusion: In this way it is possible to analyse and quantify the effect of shear connector distributions on the global and local response of continuous steel-concrete composite beams, both under service load levels and at collapse. Particular attention is focused on the ductility requirements on the shear connectors when varying the connection design approach and distribution.
