heal.abstract	In this investigation, using an energy (variational) approach, the flutter instability for various types of elastically restrained uniform cantilevers carrying up to three concentrated masses and subjected to a follower compressive force, is presented. The effects of transverse shear deformation and rotatory inertia of the mass of the column and of the positioning of the concentrated masses with or without their rotational inertia, are also included in the analysis. In all cases, where the flutter load is obtained from the coincidence of the second and third flexural eigenfrequencies a discontinuity with a finite jump in this load is possible; the lower value of the flutter load at this discontinuity is obtained from the coincidence of the first and second eigenfrequencies, while the upper value of this load is obtained from the coincidence of the second and third eigenfrequencies. Subsequently, it is found that the flutter load is a sectionally continuous function of certain of the varying parameters. Finally, the effect of several parameters upon the magnitude of the jump in the flutter load, is also discussed. © 1980.	en
