โœฆ Synopsis

The method of modal analysis is presented to investigate the random vibration of a multi-span Timoshenko beam due to a load moving at a constant velocity. The load is considered to be a stationary process with a constant mean value and a variance. The effects of both velocity and statistical characteristics of the load and the span number of the beam on both the mean value and the variance of the deflection and the moment of the structure are investigated. Moreover, the results obtained from a multi-span Timoshenko beam are compared with those from a multi-span Bernoulli-Euler beam.

A method of modal analysis is proposed in this paper to investigate the forced vibration of multi-span Timoshenko beams. The ratio of the radius of gyration of the cross-section to one span length is defined as a parameter r. The effect of r on the first modal frequency of a beam is studied. A conce

Based on Hamilton's principle, the vibration of a multi-span non-uniform beam subjected to a moving load is analysed by using modified beam vibration functions as the assumed modes. The modified beam vibration functions satisfy the zero deflection conditions at all the intermediate point supports as

In this paper, a new wave re#ector called random wave re#ector (RWR) is introduced for the control of transverse vibration and wave propagation in an in"nite, multi-span, simple-support beam. In order to illustrate the theory, RWR is "rst tested in a simple con"guration of controlling plane wave pro
