Structural system identification based on combining weighted transmissibility and wavelet transform

Abstract: In this paper, an integrated method called WTs-OMA (weighted transmissibility and wavelet transform-based operational modal analysis) is proposed to identify the structural dynamic characteristics using the earthquake response of structures. The proposed method, which is a time-frequency domain method with both parametric and non-parametric characteristics, utilizes the effective and efficient capabilities of weighted transmissibility and wavelet transform to achieve a proper performance in modal parameter est… Show more

“…Frequency is a crucial parameter in safety monitoring and damage identification of civil structures [11][12][13]. Numerous damage-identification methods that rely on frequency parameters have been explored [14][15][16][17][18][19]. The related research especially sheds light on the development of a new class of damage detection strategies that identify the damage in real time, using the key principles of the first-order eigen perturbation (FOEP) technique [4,20].…”
