Damage identification of non-classically damped shear building by sensitivity analysis of complex modal parameter

Journal of Sound and Vibration, 2019
With the increasing use of composite material and external energy dissipation device in civil structures, the classical Rayleigh damping becomes an inappropriate assumption in structural damage identification.

Structural Modal Parameter Identification Based on ARMA Model

Applied Mechanics and Materials, 2013
Structural parameter identification is a significant technology to show certain characteristics and material damage of earthquake resistant structures or building materials in structural engineering and seismic engineering field. ARMA time-series method is belonged to time-domain method.

Operational Modal Parameters Identification Using the ARMAV Model

2018
Applied system identification is an important issue in science and engineering. Experimental modal analysis is used to describe the dynamical behavior of structures, in general, for a given set of input and output data. This article deals with multidimensional modal parameters identification valid for output-only data—operational modal analysis (OMA ...

Modal parameter identification from operative responses

2006
Modal parameter estimates of a structure, vibrating under actual loadings and operational conditions, have addressed the interest of researchers during the last years. For all the developed approaches, structures need not be excited by expensive devices, because the modal signature of the structure can be achieved from the knowledge of the system time ...

Identification of Modal Parameters from Inconsistent Data

2002
Most of the recent modal parameter estimators start from the fact that natural frequencies, damping ratios and modal participation factors are global parameters of the measured structure. Measuring the structure in different patches can however cause inconsistencies in the data due to e.g. the mass-loading effect of the accelerometers.
