Identification of Sudden Stiffness Change in the Acceleration Response of a Nonlinear Hysteretic Structure
The integration of discrete wavelet transform and independent component analysis (DWT-ICA) method can directly identify time-varying changes in linear structures. However, better metrics of structural seismic damage and future performance after an event are related to structural permanent and total...
