Sažetak

The article shows the development of analytical method for the calculation of damaged reinforced concrete columns of circular cross-section. The theory and the basic settings for the calculation are based on European Eurocode standards. The paper describes the development of method, from basic assumptions (most important assumption arises in condition of the external and internal forces plain parallelism) to the final setting of five equations with five unknowns for further solving using Newton-Raphson method. The final results (via the input and resolved parameters) are given in the height of the compressed area x, the stresses in the reinforcement bars σsi and finally, in the current bearing capacity of damaged rc section N.
