Modal Parameter Identification of a Structure Under Earthquake via a Wavelet-Based Subspace Approach
Publikováno v:
Applied Sciences, Vol 14, Iss 6, p 2503 (2024)
This paper introduces a novel wavelet-based methodology for identifying the modal parameters of a structure in the aftermath of an earthquake. Our proposed approach seamlessly combines a subspace method with a stationary wavelet packet transform. By

Vibration-based damage assessment approaches are conventionally and widely adopted to monitor the structural health of a building during the bases excitation process. This study explores the possibility of using structural stiffness parameters to loc
