Nonparametric Monitoring for Geotechnical Structures Subject to Long-Term Environmental Change

<table>Time histories of the PCA eigenvalues normalized to the sum of the eigenvalues of all modes. The time history of the first mode is shown in the solid line (black), the second mode in the dashed line (red), and the third mode in the dash-dot line (blue).</table>
