Close modes are much more difficult to identify than well-separated modes and their
identification (ID) results often have significantly larger uncertainty or variability. The …

Modal parameters, including natural frequencies, damping ratios, and mode shapes, are
vital for evaluating the in-service condition of long-span bridges subjected to performance …

Bayesian operational modal analysis (BAYOMA) has been increasingly applied to ambient
vibration tests, providing a fundamental means for estimating modal properties as well as …

Operational modal analysis (OMA) aims at identifying structural modal properties with
(output-only) ambient vibration data. In the absence of loading information, the identification …

This paper investigates the challenges in accurately identifying and assessing vibration
characteristics in automotive disk brakes, which, due to their geometric symmetry, exhibit …

ABSTRACT Two‐dimensional (2D) Eu‐Bi12O17Cl2 nanosheet binary composites modified
by Bi2S3 nanocrystals were constructed at room temperature using a simple in situ anion …

Operational modal analysis (OMA) identifies the modal properties, eg, natural frequencies,

During bridge service, material degradation and aging occur, affecting bridge functionality.
Bridge health monitoring, crucial for detecting structural damage, includes finite element …

Variations of structural dynamic parameters (eg, frequencies and damping ratios) can be
caused by potential structural damages and environmental effects (eg, temperature …

The design and assessment of structural dynamics behaviour often rely on the 'modal
properties'(primarily modal frequencies, damping ratios and mode shapes) of a structure …
