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.
