Vibration Performance Assessment of a Long-Span Concrete Floor Using Field Measurements Over a Five-Year Period

Jun Chen, +2 more
- 01 Aug 2014 - 
TL;DR: In this article, the authors assess the vibration performance of the floor using field measurements and identify the natural frequencies, damping ratios, mode shapes and modal masses of the concrete floor.

Modal Model Identification with Unknown Nonstationary Base Motion

Danilo Capecchi, +2 more
- 01 Feb 2004 - 
TL;DR: In this paper, the authors describe the theoretical aspects of a technique they have recently developed to identify the modal model in the frequency domain when the input is unknown, and they show that from a theoretical point of view, the identification problem has a unique solution, for this kind of input, when at least three time histories are known, and this circumstance had never been pointed out before.

Automated reduction of statistical errors in the estimated correlation function matrix for operational modal analysis

Marius Tarpø, +5 more
- 01 Oct 2019 - 
TL;DR: In this paper, the authors proposed an automated algorithm that reduces the bias error caused by the statistical errors by identifying erratic behaviour in the tail region of the modal correlation function and reducing this noise tail.

Wet Damping Estimation of the Scaled Segmented Hull Model Using the Random Decrement Technique

Yooil Kim, +1 more
TL;DR: In this paper, a segmented hull model using a random decrement technique together with a continuous wavelet transform was used to estimate the damping ratio of 16 sea states and the wet natural frequencies.

Experimental studies on damage detection in frame structures using vibration measurements

Giancarlo Fraraccio, +2 more
- 01 Jan 2010 - 
TL;DR: In this article, the authors presented an experimental study of frequency and time domain identification algorithms and discussed their effectiveness in structural health monitoring of frame structures using acceleration input and response data using a four-story steel frame model on a uniaxial shake table.
