Sažetak
The paper deals with accurate determination of the relationship between bending moment and curvature of hollow rectangular bridge columns. With the calculation procedure to determine accurate curve of relationship, the method of determining the idealized diagram typically used in practice is also shown. The aim of this work is to point to a reserve in load capacity of an element when comparing the results of an accurate curve and the idealized diagram, and to analyse the impact of various calculation situations on the curve shape. The conclusion is that for practical use it is sufficient to use the idealized diagram, but for detailed scientific analysis the exact relationship between bending moment and curvature must be determined.
