A numerical procedure based on the finite element method for the analysis of reinforced concrete beam-columns under uniaxial bending is presented. Material nonlinearities such as the cracking and crushing of concrete and the yielding of reinforcing steel as well as the geometric nonlinearity which is an important factor affecting the behavior of beam-columns are considered in the analysis. This method traces the behavior of reinforced concrete beam-columns up to failure by solving incremental equilibrium equations, Numerical examples are presented to demonstrate the validity and usefulness of the present method.
