Abstract
The aim of this work is to examine the influence of some structural parameters, namely, the mass per unit length and flexural rigidity of the upper beam on the natural frequencies of a symmetric non-prismatic double-beam system elastically connected by a Pasternak-type layer. A semianalytical technique known as differential transform method was used to carry out the analysis of the vibration problem in this paper. The results of the analysis revealed that there is tendency to lower the vibration frequency of the double-beam system by increasing the mass of the upper beam. It was also found that the natural frequencies of the double-system generally increase with an increase in the flexural rigidity of the upper beam of the double-beam system. It can be concluded that both the mass per unit length and the flexural rigidity of the upper beam generally have influence on the natural frequencies of a non-prismatic double-beam system elastically coupled by a Pasternak-type elastic medium
