TL;DR: An exact solution of the title problem is presented in this paper, where three boundary conditions for the structural element are considered: simply supported, simply supported - clamped and clamped at both ends, and an analysis of the situation where the spring mass system acts as a dynamic absorber cancelling out the motion at the point of attachment for certain modes of vibration is presented.

TL;DR: In this article, the free vibration of a beam hinged at one end by a rotational spring and subjected to the restraining action of a translational spring at the other end is dealt with.

TL;DR: In this paper, the lower natural frequencies of vibration of the structural system described the title have been determined and are presented for a significant range of values of the governing mechanical and geometric parameters for two types of configurations of structural interest: discontinuous variation of the thickness and continuous, linear variation.

TL;DR: In this paper, the fundamental frequencies of vibration of the structural elements as determined by the methodologies (a) and (c) are in excellent agreement while rather considerable discrepancies are found when using the differential quadrature technique.

TL;DR: In this article, the influence of the shear flexibility on the out-of-plane free vibration of continuous horizontally curved thin-walled beams with both open and closed sections was studied.
