... is proposed. Firstly, the autoregressive (AR) model is used to fit the structural acceleration response pre and post damage. Secondly, the principal component analysis (PCA) is employed to remove the influences of environmental conditions on the coefficients of AR model. Mahalanobis norm calculated from...
