    Joint approximate diagonalization technique for modal identification of the Donghai Bridge by Ben Li, Lin Chen, Satish Nagarajaiah, Limin Sun

    Published 2025-01-01
    “…Abstract The second-order blind identification (SOBI) and its variants have been extensively explored for output-only modal identification of civil structures under varied excitations. At the core of these methods is the matrix joint approximate diagonalization (JAD) technique, while their efficiency and accuracy are largely determined by how the target-matrices for JAD are constructed from multi-channel structural responses. …”
