Seismic Damage Detection of Moment Resisting Frame Structures Using Time-Frequency Features
To detect seismic damage of moment equi-jec 6 resisting frame (MRF) structures, a data-driven method using the fractal dimension (FD) of time-frequency feature (TFF) of structural seismic dynamic responses at measured stories is extended and refined.The TFF is defined as the real part of Gabor wavelet transform of translational interstory displacem
