Study on Non-Linear Flexural Behavior of Reinforced Concrete Beams Using ANSYS by Discrete Reinforcement Modeling

Experimental testing and non-linear finite element analysis using discrete reinforcement modeling of six numbers of reinforced concrete beams under four-point bending are presented in this paper. Finite element modeling of reinforced concrete beams is carried out using ANSYS 12.0, and the critical values of the results are also compared with analytical values calculated using IS 456: 2000 codal provisions. Wide-range graphical display of the results such as deflected shape of the beam, stress-strain variation along the length and depth of the beam and crack propagation is generated by creating a batch file using the ANSYS parametric design language. Comparison is made between the test results, finite element analysis and analytical values with respect to initial crack formation and the ultimate capacity of beams, in order to have a wide understanding on the behavior, which may reduce the physical destructive laboratory testing for the future researchers.
