An Improved Damage Detection Method and Its Application

摘要：

　　A new method called Grey Relation Modal Flexibility Curvature Difference (GRMFCD)is proposed and applied to the numerical experiment and experimental research of a substructure.The results show the ability of GMFCD to locate the inflicted damage and qualitatively evaluate its severity for single and multiple scenarios,with only a few lower order modal parameters.The effectiveness and advantages of GMFCD as compared to the flexibility indicators,such as the change in flexibility,the curvature of the flexibility difference,are demonstrated.
