Annotation	The contribution includes the results of experimental works aiming to find a new methodology for the calculation of fatigue life of structures subjected to operational loading from a combination of forces and moments of random character.The power spectral density indicating the power at individual frequenciesyields information about the suppliied amount of energy.Therefore , it can be assumed that thewre is a dependence between the PSD shape and the size of damage.The searching for links between the PSD of the loading process and the fatigue life of structure under load is dealt with by new Grant.
