Advances of Vibration-based Damage Identification Methods

Detection, location and qualification of damage in engineering structures are very important topics of research, due to increasing demands for quality and reliability. The research effort to use changes in vibrational modal parameters (frequencies and modes) to identify structural damages in civil engineering has increased during recent two decades. Vibration_based damage identification methods are summarized in the present paper. Some basic problems of vibration_based damage identification technology and the past, current applications of the technology to civil engineering are discussed. Comments on some current methods in the literature are made. Critical issues for future research in the area are also presented.
