A Genetic Algorithm for Structural Damage Detection Based on Vibration Data
1. INTRODUCTION In this paper genetic algorithm with real number encoding is applied to identify the structural damage with vibration data. The objective function is minimized by directly comparing the changes in the measurements before and after damage, rather than updating the finite element model in the undamaged and damaged states. Three different criteria are considered, namely the frequen...
متن کاملA novel method for detecting structural damage based on data-driven and similarity-based techniques under environmental and operational changes
The applications of time series modeling and statistical similarity methods to structural health monitoring (SHM) provide promising and capable approaches to structural damage detection. The main aim of this article is to propose an efficient univariate similarity method named as Kullback similarity (KS) for identifying the location of damage and estimating the level of damage severity. An impr...
متن کاملA Summary Review of Vibration-based Damage Identification Methods
This paper provides an overview of methods to detect, locate, and characterize damage in structural and mechanical systems by examining changes in measured vibration response. Research in vibration-based damage identification has been rapidly expanding over the last few years. The basic idea behind this technology is that modal parameters (notably frequencies, mode shapes, and modal damping) ar...

متن کاملVibration-Based Techniques for Damage Detection and Health Monitoring of Mechanical Systems
The state of the art in vibration-based damage detection and health and usage monitoring is reviewed. The damage detection concepts and the signal analysis techniques are examined, explained, and compared. Latest advances in signal processing methodologies that are of relevance to vibration based damage detection (e.g., Wavelet Transform and Wigner-Ville distribution) are highlighted. These vib...
