An Approach to the Moving Load Problem for Multiple Cracked Beam

  • Conference paper

Topics in Modal Analysis, Volume 7

Abstract

The present report is devoted to present an approach to dynamic analysis of multiple cracked Euler-Bernoulli beam subjected to general moving load. The novelty of the approach consists of using analytical solution of vibration mode of multiple cracked beam in the frequency domain that is straightforward to compute the time response of multiple cracked beam to moving load given generally in a discrete form. The proposed method enables to eliminate the “moving singularity” phenomena that trouble the use of either the conventional modal method or the modern numerical techniques. The theoretical development is illustrated by numerical results.
