✦ Synopsis

The dynamic response of a non-uniform continuous Euler}Bernoulli beam is analyzed with Hamilton's principle and the eigenpairs are obtained by the Ritz method. A high-precision integration method is used to calculate the dynamic responses of this beam. Numerical results show that the method is more accurate in the prediction of the vibration responses under the moving loads than the Newmark method.

Analytic expressions of the dynamic ampli"cation factor and the characteristic response spectrum are derived for weakly damped beams with various boundary conditions subjected to point loads moving at constant speeds. These coe$cients are given as functions of the ratio of the span length to the loa
