This paper deals with the dynamic analysis of infinite beam models. The translational and the rotational dynamic stiffness of both Timoshenko and EulerβBernoulli beams on Winkler foundation are derived and compared in the frequency-domain. The situation of vanishing elastic foundation is included as
The dynamic sti!ness matrix of an in"nite Timoshenko beam on viscoelastic foundation to a harmonic moving load is established. This dynamic sti!ness matrix is essentially a function of the velocity and frequency of the harmonic moving load. The critical velocities and the resonant frequencies can be
An asymptotic solution is presented for the natural frequencies, mode shapes of a cantilevered, coupled beam model. A three-term expansion is obtained for the frequency, which shows good agreement with exact values over a wide range of the stiffness parameter Ξ±. The first three mode shapes are also
