A statistical research of the calculation methods for calculating ultimate moments of concrete elements reinforcedwith fibre-reinforced plastic is presented. For this purpose a database of experimental results has been collected.Calculations of the ultimate moment resistance were performed according to three design recommendations.Wilk-Shapiro test were used to determine the distribution of experimental and theoretical data. The statistical researchto evaluate the calculation methods was performed by testing the statistical hypothesis on the differences betweentheoretical and experimental values. It is suggested to calculate the coefficient of confidence for assessing the accuracyof calculation methods.
