Modified damage identification algorithm based on vibration measurements

Abstract

In this paper, a newly derived algorithm to detect damage and predict its location in structures using changes in vibration measurements is presented. First, an existing algorithm of damage detection is reviewed and the new algorithm is formulated in order to detect damage and improve the accuracy of damage localization using low frequency range. Compared to the existing damage detection algorithm, the new algorithm showed the ability to detect and localize damage more accurately using very low frequency range without the need for measuring higher modes.
