Abstract
A time-frequency tool based on wavelet analysis is employed to investigate
the dynamic responses of concentrically-braced frames tested in shake table
tests. It is shown that the application of wavelet analysis allows yielding and
buckling events to be detected from a limited set of measurements, namely
ground and building floor accelerations. This is achieved by comparing
frequency-banded wavelet coefficients of the ground motion, elastic frame
response and inelastic frame response, and by evaluating the corresponding
energy contributions of the different frequency bands.
