... In another study, Filipich et al. [3]determined the fundamental frequency of vibration of a frame elastically restrained against translation and rotation at the ends, carrying concentrated masses by using the Rayleigh-Ritz method. Filipich et al. [4] dealt with the analysis of the first symmetric mode of vibration of a generally restrained frame with non-prismatic members carrying concentrated masses. ...

... Having employed different methods such as theoretical, numerical, and experimental ones, many interested researchers intended to study the dynamic behavior of the rings [5][6][7][8][9][10][11]. In order to obtain more accurate results and to better simulate the actual operational conditions, researchers have considered many various assumptions in deriving of equation of motion such as transverse shear strain, rotatory inertia, warping, nonuniform cross-section and different boundary conditions [12][13][14][15][16][17][18][19][20]. Moreover, dynamic behavior as well as the stability of rotating rings has been studied in different rotation conditions in the following references [2,3]. ...

... This is why the study of the vibration properties of frame structures continues to be a subject of significant interest among scholars. [1][2][3][4] In the analysis of vibration characteristics of plane frames, the primary theories employed are based on either the Euler-Bernoulli beam model or the Timoshenko beam model. Over the last two decades, considerable progress has been made in the study of vibration characteristics of plane frames, resulting in the development of a diverse array of computational methods. ...
