Output-only modal identification has seen significant activity in recent years, especially in
large-scale structures where controlled input force generation is often difficult to achieve …

This paper investigates the problem of modal parameter estimation of time-varying
structures under unknown excitation. A time–frequency-domain maximum likelihood …

Aging of infrastructure causes many problems with great consequences, essentially
economical. Operation modal analysis (OMA) is one of the most crucial techniques used for …

Modal analysis together with finite element method (FEM) has evolved as a key technology
in dynamic characterization of structures. The traditional modal analysis, known as …

The polyreference least-squares complex frequency (PLSCF) modal parameter estimation
algorithm has gained some popularity since the introduction of its single-reference …

Experimental dynamic characterization of a wind turbine, operating under variety of
conditions, is a desired task as it provides useful insights that can be used for number of …

Modal analysis is a critical part of the automotive development process. Identification of the
vehicle's modal signature, especially in the low-frequency end of the spectrum, is essential …

Abstract The field of Operational Modal Analysis (OMA) has recently become an emerging
research interest. OMA, also known as Response-Only Modal Analysis, extracts the modal …

Changes in natural frequencies, modal shapes, and dam** ratios of a two story single
span reinforced concrete building having different stirrup spacing in columns are analysed …

Modal parameters of large civil engineering structures such as modal dam** ratios
(MDRs) are determined mainly by output-only modal identification. In this paper, MDRs of a …
