The objective of the paper is to analyze the efficiency of design methods proposed in different codes according to the load carrying capacity of concrete structures. In particular, three standard recommendations have been considered: the ACI 318 shear design model, the equation by Eurocode 2 and a new design procedure from Model Code 2010. In the paper the flexural concrete members, which are reinforced longitudinally but without transverse reinforcement, are considered. The design values of the load carrying capacity of such members obtained from these three codes were compared with experimental results. An advanced statistical analysis has been applied to predict of dependent variable (load carrying capacity of tested beams) and to perform a comparative analysis. On the basis of the analysis conclusions have been drawn according to the fit between the design methods and the test data.
