Vibrations are the root cause of many mechanical and civil structure failures. Dynamic
characteristics of a structure must be extracted to better understand structural vibrational …

Operational modal analysis (OMA) is used to identify the modal parameters of a structure
under operational conditions, which reflects the real boundary conditions and state …

We present a novel approach to harmonic disturbance removal in single-channel wind
turbine acceleration data by means of time-variant signal modeling. Harmonics are …

Many parameters can be used to express a machine's condition and to track its evolution
through time, such as modal parameters extracted from vibration signals. Operational Modal …

Mass timber construction has been gaining momentum in multi-story residential and
commercial construction sectors in North America. As taller mass timber buildings are being …

An experimental program of a 1: 6 scale elevated wood frame shear-wall residential building
was developed to model the damage progression of buildings subjected to increasing …

The presence of deterministic harmonic excitation, such as that induced by rotating
machinery, violates the classical operational modal analysis (OMA) assumption that the …

Uji beban dinamik bertujuan untuk mengetahui tingkat keselamatan, keamanan dan kondisi
awal kelaikan operasi jembatan. Penentuan kelaikan didasarkan dari penilaian parameter …

Harmonics are signal components with energy concentrated at single frequencies and are
often of special interest in vibration analysis. Depending on the application, harmonics are …

The dynamic behavior of a rotating machine consists not only of the response of the shaft,
but it also contains information of all supporting structures and equipment interacting with …
