In this paper, the studies on an influence of the parameters of the loading heads on the stability and free vibrations as well as on loading capacity of the cracked column subjected to a specific load are presented. The defect of the host structure has a form of a crack and is simulated by means of the rotational spring. The boundary problem is formulated by use of Hamilton’s principle on the basis of which the differential equations of motion as well as natural boundary conditions are obtained. The main scope of this study is to estimate an influence of the parameters of the loading heads on stability and free vibrations as well as on loading capacity of the cracked column. Finally, the numerical simulations are compared to the experimental ones.
