Operational modal analysis on the hydroelastic response of a segmented container carrier model under oblique waves

Yooil Kim, +3 more
- 15 Nov 2016 - 
TL;DR: In this paper, a segmented hull model of a 10,000 TEU container carrier with the scale of 1/60 was towed in a model basin under head and oblique waves and the strain time histories at designated locations along the continuous backbone were measured.

An Example of Correlation Matrix Based Mode Shape Expansion in OMA

Rune Brincker, +2 more
TL;DR: In this article, the authors used the correlation matrix for the filtered response including all measured DOFs as a basis for the mode shape expansion, which contains the normal modes that can easily be extracted from the column space of the correlated matrix.

Field tests and verification of damping calculation methods for operating highway bridges

Ali Zarafshan, +2 more
- 01 Jan 2014 - 
TL;DR: In this article, the decay of motion direct measurement and the natural excitation technique were used to determine damping in an operational highway bridge using two approaches, namely, the decay-of-motion direct measurement (DOMM) and the NEM technique.

Method for Identification of Grouting Continuity of Rock Bolts

Andrzej Staniek
- 01 Jan 2005 - 
TL;DR: In this article, a method for non-destructive identification of discontinuity of a resin layer surrounding rock bolts is presented, based on an impact excitation where a response transducer is positioned at a visible part of a rock bolt.

Wet Damping Estimation of the Segmented Hull Model using the Random Decrement Technique

Yooil Kim, +1 more
- 20 Aug 2013 - 
TL;DR: In this article, the authors presented the wet damping estimation of the segmented hull model using the random decrement technique together with the continuous wavelet transform, where the tested 16 sea states were grouped together based on the speed of the ship in order to figure out the possible influence of ship speed on the damping ratio.
