In this paper, the free vibration characteristics of
an elastically connected non-prismatic double-beam system
based on Euler-Bernoulli beam theory are determined using
differential transform method. The double-beam system is
composed of two parallel non-uniform cantilever beams which
are attached to each other by a Pasternak elastic medium.
Numerical results of the method used are validated by
comparing with the ones available in the published literature.
The effect of the taper ratio on the natural frequency of the
double-beam system is also studied
