This study details the investigation of the non-linear vibrations of a column consisted of two rods, one of which is made of piezoceramic material. The actuator, possessing its flexural stiffness is discretely attached to the main carrying rod. The role of the piezoelectric force generated by the actuator is to moderate the flexural displacement of the column which arises due to an unintensional eccentricity of the external load. The piezoelectric force influences also the natural frequency of the system, which tends to zero for the growing values of the external load.
