Abstract
Behaviour of reinforced concrete is typically studied by full-scale experimental investigations. Finite element software’s are used to validate the results of these experimental studies. Many researchers proved the assurance of the analysis techniques of reinforced concrete with FEM software by comparing the results with experimental study. In the present paper three models of reinforced concrete beams are used to model the effect of percentages of steel reinforcement in flexural behavior as under, balanced and overreinforced beams. Nonlinear finite element analysis is used to analyze reinforced concrete beams up to failure with FEM software ANSYS. Reinforced concrete beams subjected to the four points bending, are modeled considering the frequent use in the laboratory. The percentages of steel required for the beam to become under, balanced and overreinforced are calculated using codal provisions of I.S. 456-2000 code.
