Conference Programme Gijón – Spain 12-14 May 2015

6th IOMAC INTERNATIONAL OPERATIONAL MODAL ANALYSIS CONFERENCE

6th International Operational Modal Analysis Conference

1

Welcome to IOMAC 2015 Welcome to the 6th International Operational Modal Analysis Conference, Gijón, Spain, May

12‐14, 2015.

The Conference is jointly organised by the University of Oviedo and the Technical University

of Madrid, with the assistance of the L’Aquila University. For the first time, the IOMAC

Conference is running for three days from Tuesday to Thursday, whereas the Pre‐Conference

lasts two days from Sunday to Monday.

The 6th edition of IOMAC is dedicated, in memoriam, to Prof. Francesco Benedettini who

passed away in February 2015. He was an active member of the IOMAC Scientific Committee

and served as a chair of the conference in 2009 and as the chair of the Permanent

Committee since May 2013. The IOMAC community had the pleasure and honor to work

with Prof. Francesco Benedettini and all of us are very grateful for the important

contributions to IOMAC that he made over the years.

Nowadays, Operational Modal Analysis (OMA) is a clear alternative to traditional modal

analysis in structural dynamics. In the last years OMA has experienced an enormous progress

from which many reliable techniques have emerged for solving all kind of problems in the

real world. This is confirmed by the substantial number of papers published in journals and

Conferences but also by the first OMA books including theory and practice related to OMA.

This Conference covers all major aspects of Operational Modal Analysis, with focus on the

following topics: Identification Techniques, Measurement Techniques, Applications in Civil

Structures, Applications in Mechanical Structures, Comparison with Traditional Modal

Analysis, Model Validation and Model Updating, Structural Modification, Structural Health

Monitoring and Wind Turbines.

Beyond a good number of interesting papers on these topics, presented by researchers,

technical specialists and students, the Conference comprehends an Honorary Lecture by

Dr. Håvard Vold and two Keynote Lectures by Dr. Dmitri Tcherniak and Professor Rune

Brincker, three prestigious members of the OMA community.

As the previous IOMAC Conferences, held in Copenhagen (2005 and 2007), Ancona (2009),

Istambul (2011) and Guimaraes (2013), scientists, applicants, vendors and students have the

occasion to share their knowledge in this rather fascinating field and to improve their

specific skills.

We warmly thank all the contributors, authors, speakers and exhibitors and sponsors of the

event and wish this conference offering you fruitful discussion and a pleasant time in Gijón.

Notes for chairs and speakers

• The IOMAC conference will be running on a tight schedule and your cooperation in

making sure the sessions follow to the designated time limit is much appreciated.

• Each Speaker is allowed a total of 20 minutes: 12‐15 minutes for Oral Presentation +

5‐8 minutes for short Questions and Answers (Q&A).

• Speakers will be alerted as they approach their presentation time limit (i.e. with a 2‐

minutes warning). We suggest all Speakers to prepare a presentation with about one

slide per minute (maximum of about 15‐20 slides).

• The short CV (submitted together with the paper) will be used by the Chair to

introduce the Speaker before the presentation.

• A computer with projector equipment will be available at each conference room. The

computers are equipped with USB ports. Authors must bring their presentation on a

USB memory key (flash drive) to the room where their presentation is being given to

preload it on the presentation laptop. Authors are free to use their own laptop for

their presentation, but must ensure compatibility with the LCD projector prior to the

start of their session. The computers will be running Windows 7/8 with MS Office

2013 and the latest version of Acrobat Reader. For presentations we advise to use

power‐point or pdf slides.

Structural Vibration Solutions A/S is the developer of ARTeMIS Modal software. The

patented operational modal analysis software is for the vast number of cases where it is

preferred not to control or measure the loading. If you can measure the vibrations, ARTeMIS

Modal can give you the modes in terms of mode shape, natural frequency and damping

ratio. We will present latest features in the upcoming ARTeMIS Modal Pro 4.0: Harmonics

Removal Tool, Modal Parameter History with automatic mode tracking, Damage Detection,

Drift Analysis, and the brand new 3D Data View.
