Post-Earthquake Damage Identification of Buildings with LMSST

The structure is said to be damaged if there a permanent shift in the post-event natural frequency of as compared with pre-event frequency. To assess damage structure, time-frequency approach that can capture and required. In this study, determine these frequencies, local maximum synchrosqueezing transform (LMSST) method employed. Through simulation results, we have shown traditional methods such Wigner distribution, Wigner–Ville distributions, pseudo-Wigner–Ville smoothed transforms are not capable capturing structure. amplitude signal captured by sensors during those events very small seismic event. Thus, cannot post-event, whereas LMSST employed work easily identify frequencies. This attribute makes it attractive for post-earthquake detection. claims qualitatively quantitatively substantiated comprehensive numerical analysis.
