Abstract
Description
The article deals with natural vibrations of the spatial axisymmetric dome shaped structure. The variational formulation of the problem arising from the principle of possible displacements is carried out. To solve the problem, an algorithm and computer programs have been developed using the semi-analytical finite element method (FEM). The non-axisymmetric natural frequencies and vibration modes of the investigated object have been determined. The results obtained are analyzed in order to detect mechanical effects
