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
