Generalized eigenvalue decomposition in time domain modal parameter identification

Wenliang Zhou, +1 more
- 01 Feb 2008 - 
TL;DR: This paper is intended to point out the relationship among current time domain modal analysis methods by employing generalized eigenvalue decomposition, and shows that single-input multioutput (SIMO) methods can easily be extended to multi-inputmultioutput (MIMO) cases by taking advantage of a generalized Hankel matrix or a generalized Toeplitz matrix.

Investigations of harbour brick structures by using operational modal analysis

Mariusz Żółtowski
- 01 Jan 2013 - 
TL;DR: In this paper, an attempt to investigate the destruction process of selected building structures by using the method of operational modal analysis was made, and the authors concluded that the effect of vibrations to structure is mainly manifested by additional stresses in a given cross section, which are summed up with those resulting from static loads.

System identification of torsionally coupled buildings

Jin-Min Ueng, +2 more
- 01 Feb 2000 - 
TL;DR: In this paper, an extended random decrement method was employed to reduce the measured dynamic responses of general torsionally coupled multi-story building under random excitations, which is able to identify structural dominant modal parameters accurately even with highly coupled modes and noise contamination.

(Smart Materials and Structures, 14(4):850-861)Parametric Identification of Asymmetric Buildings From Earthquake Response Records

C. C. Lin, +4 more
TL;DR: In this paper, the modal frequencies, damping ratios and mode shapes of an asymmetric building, modeled as general torsionally coupled buildings using a modified random decrement method together with the Ibrahim time domain technique based only on few floor acceleration response records from earthquakes.
