 Summary:
 In this paper, nonlinear behavior of reinforced concrete beam, subjected to monotonically increasing load and designed according to EN 1992-1-1, was analyzed. For discretization of the concrete member part, 3-dimensional finite elements, SOLID65, in the program Ansys, 2-dimensional finite elements, CPS4, in the program Abaqus and 2-dimensional finite elements, 2D Solid, in the program ADINA were applied. The reinforcement was modeled using the basic rod and beam finite elements. Numerical analyzes were done on the spatial model in the program Ansys and simplified twodimensional models with the assumption of a plane stress condition in Abaqus and ADINA programs. The results of the analysis of the stress-strain state and the vertical displacement of the beam mid-span are presented.
