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 …

The main limitations in the finite element (FE) model updating technique lie in the ability of
the FE model to represent the true behavior of the structure (modelling problem), and in the …

The literature about the mass associated with a certain mode, usually denoted as the modal
mass, is sparse. Moreover, the units of the modal mass depend on the technique which is …

Image-based optical vibration measurement is an attractive alternative to the conventional
measurement of structural dynamics predominantly relying on accelerometry. Although …

In combined vibration testing, an artificial, measured force is used in operational conditions.
This requires the identification of a system model that takes both the measured and the …

This paper addresses and evaluates the influence of different types of dynamic excitation
sources on identifiability and reliability of modal parameter identification of an eleven-span …

Modal parameters comprise natural frequencies, damping ratios, modal vectors and modal
masses. In a theoretic framework, these parameters are the basis for the solution of vibration …

Today, short-and long-term structural health monitoring (SHM) of bridge infrastructures and
their safe, reliable and cost-effective maintenance has received considerable attention. From …
