A new method is proposed for the study of the failure mechanism of reinforced concrete sections of arbitrary shape in biaxial bending with axial force. The procedure is an alternative fiber model which employs computer graphics as a computational tool for the integration of normal stresses over the section area. In addition to the cases of classic reinforced concrete sections with longitudinal reinforcement steel bars, the method is extended to sections of reinforced concrete structural members repaired by jackets as well as to members with composite steel-concrete sections. Such a computational tool satisfies the needs of nonlinear analysis of reinforced concrete structures as well as the needs of the daily design practice. The method does not include any iterative procedure within its steps and thus it does not have the disadvantage of possible nonconvergence. On the other hand, it is fast and gives accurate results. Four representative numerical applications of the method are presented for the clarification of its validity and advantages.
