Review of vibration-based structural damage identification methods

Structural damage detection methods using vibration parameters are reviewed here. The necessity and the urgency to conduct safety assessment, health monitoring and damage diagnosis are introduced. Damage identification techniques in recent years are classified and illuminated briefly. Methods based on model updating and techniques without finite element model are discussed particularly. Damage detection algorithms using time-domain identification procedure, wavelet transformation and neural network are also reviewed. The advantages and shortcomings of these damage identification methods are analyzed. Several key issues related to structural damage identification are emphasized and future study aspects are pointed out.
