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 deals with the estimation of modal parameters from vibration
data obtained in operational rather than laboratory conditions. This paper extensively …

Comprehensively covers the basic principles and practice of Operational Modal Analysis
(OMA). Covers all important aspects that are needed to understand why OMA is a practical …

Structural health monitoring and damage detection techniques are tools of great importance
in the off-shore, civil, mechanical and aeronautical engineering communities, both for safety …

The modal analysis of mechanical or civil engineering structures consists of three steps:
data collection, system identification and modal parameter estimation. The system …

This tutorial paper aims to introduce the topic of operational modal analysis to non-
specialists on the subject. First of all, it is stressed the relevance of this experimental …

A sensitivity-based finite element (FE) model updating is carried out for damage detection in
this paper. The objective function consisting of the modal flexibility residual is formulated …

An approach to identify modal parameters from output-only transmissibility measurements is
introduced. In general, the poles that are identified from transmissibility measurements do …

Modal substructuring or component mode synthesis (CMS) has been standard practice for
many decades in the analytical realm, yet a number of significant difficulties have been …

Many important systems, such as wind turbines, helicopters and turbomachinery, must be
modeled with linear time-periodic equations of motion to correctly predict resonance …
