A time-frequency tool based on wavelet analysis is employed to investigate the dynamic responses of concentrically-braced frames tested in shake table tests. Damage in the form of brace yielding and buckling is detected by comparing table and roof accelerations using wavelet analysis. This comparison is carried out by examining frequency-banded wavelet coefficients of the ground motion and elastic/inelastic frame response, and by evaluating the corresponding energy contributions of the different frequency bands.
