✦ Synopsis

The problem of lateral vibration of an axially loaded infinite uniform Bernoulli-Euler beam is investigated by setting up a model of the infinite beam with a harmonically varying, transverse concentrated force at the centre of the beam. A static axial load either tensile or compressive is applied to the beams. The elastic and stiff discrete supports are treated in the analysis. The influences of the axial load on the vibration modes and resonance frequencies of the beams are studied. Some numerical results such as the varying characteristics of resonance frequencies and the corresponding maximum amplitudes of the central deflection are presented with attention focused on the effect of axial load on vibration of the beam.
