000010076 520__ $$2eng$$aIn the last decades a great effort has been made to obtain accurate evaluation of the resistance of reinforced concrete elements subjected to pure shear or combined internal forces including shear. In regard to this latter subject, continuum models characterized by simplified stress fields have recently been applied by some of the Authors for the evaluation of the ultimate capacity interaction diagram of rectangular reinforced concrete cross-sections undergoing combined axial force, bending moment and shear force. The present paper constitutes the natural progress of these studies and describes an analytical tool for the calculation of the ultimate capacity interaction diagram of reinforced concrete columns with circular cross-section. The proposed method is based on the application of the static theorem of limit analysis and requires the definition of equilibrium equations and boundary conditions for geometrical and mechanical parameters. In order to validate the method, the relations developed are applied with reference to many laboratory models tested in the past and the theoretical results are compared to the experimental ones.
