A Study on Nonlinear Finite Element Analysis of Reinforced Concrete Plates

In this study, Finite Elements Method was used for the nonlinear analysis of reinforced concrete plates under gradually loading conditions beginning from zero load to failure load. Layered Composite Material Model was used for the modeling of reinforced concrete plates. The principles of this approach is given in “layered composites mechanics” that it was successfully applied for the nonlinear analysis of reinforced concrete plates. This approach differs from the other approaches by considering the effect of tensile rigidity of the concrete between cracks and by using a criterion based on the crack energy concept together with the consideration of the effect of finite element network dimension. Load-displacement relationships were determined according to the Layered Composite Material Approach. The results of the analyses were compared and found to be in agreement with the experimental results and the results of past studies. A computer program prepared with Fortran PowerStation 4.0 programming language was used for the determination of this study’s results.
