APPLICATION OF PATTERN RECOGNITION TO DAMAGE LOCALIZATION

Pattern recognition is used as a basis to localize damage in structures. Feature vectors that depend on the predamaged and postdamaged mode shapes are developed. Classification criteria are developed to classify elements in the feature space into damaged and undamaged classes. The formulation is applied to a three-dimensional finite element model of a bridge girder. The accuracy of the localization results is then evaluated.
