Damage Identification by the Data Expansion and Substructuring Methods

Figure 9

Damage detection using the expanded noise-free measurement data: (a) displacement variations; (b) stiffness variation rate at lower chords; (c) stiffness variation rate at upper chords; (d) stiffness variation rate at “/”-type diagonal elements; (e) stiffness variation rate at “\”-type diagonal elements; (f) stiffness variation rate at vertical elements. In (a), the solid line indicates the horizontal displacement and the dashed line indicates the vertical displacement.
