Operational modal analysis of civil engineering structures with closely spaced modes based on improved hilbert–huang transform

HIGHLIGHTS

  • What: In this study an HHT analytical mode decomposition (AMD) is proposed and is used to identify the modal parameters of structures with closely spaced modes.
  • Who: Xu-Qiang Shang et al. from the School of Civil Engineering, Central South University, Changsha, China have published the research: Operational Modal Analysis of Civil Engineering Structures with Closely Spaced Modes Based on Improved Hilbert-Huang Transform, in the Journal: Sensors 2024, 24, x FOR PEER REVIEW of /2024/
  • How: Based on the obtained free decay responses the modal parameters of the simulated high-rise building . . .
