Structural concrete members like beams, shear walls, slabs, shells etc., are mostly assumed to be subjected to biaxial stress states. Several numerical methods were developed to analyze these concrete members exposed to biaxial stress conditions. In this study, the non-linear finite element method is used to analyzed the concrete prism and the reinforced concrete beam by using the octahedral constitutive relations, and the results are compared with the plastic analysis output of the ANSYS program with Drucker-Prager yield criterion.
