Sunday 12th 2019: Optional activity related to the Operational Modal Analysis Course

You can participate in this part of the course without any further expense. Just write a mail to Line Leth Christiansen Lilch@byg.dtu.dk to notify your interest. This activity will take place at DTU, will cover the OMA testing of different small models, and will extend over both morning and afternoon.

Curriculum Vitae for Svend Gade:

Svend Gade joined Brüel & Kjær, Nærum, Denmark in 1980, where he has been working as an application specialist and as Associate Professor at the Brüel & Kjær University Group in the Sound & Vibration Measurement segment until his retirement in 2017. He is now a consultant with own company, Gade S&V. Gade was heavily involved with the introduction of the world’s first commercially available Sound Intensity system in the 1980es, and he wrote several B&K Technical Reviews covering this topic. He has continued working in this field with array acoustics, i.e. Acoustical Holography and Beamforming techniques. His main focus over the years has been Modal Analysis starting when the modern era of structural measurements began in the 1982 introducing worldwide the concepts of Dual Channel Analysis and input/output measurements techniques. Since 1999 he has also worked with the development of output only modal analysis, i.e. Operational Modal Analysis. His other responsibilities included digital signal analysis, sound power, signature analysis, machine diagnostics, and Sound Quality. He has presented more than 150 papers at conferences such as SAE, JSAE, Inter-noise, ICSV, IMAC, ISMA and IOMAC. Gade has written more than 50 major articles including 20 articles in Sound & Vibration Magazine and 20 Brüel & Kjær Technical Reviews and a chapter in “Handbook of Noise and Vibration Control” (John Wiley & Sons, Inc.). He has lectured extensively throughout the world including Japan, China, India, Australia, Brazil and USA. Gade holds a M.Sc. degree from the Danish Technical University in Copenhagen in electronics/acoustics in 1973 and is educated in 1980 as a lecturer as well. Gade is member of Institute of Noise Control Engineering, INCE, Society for Experimental Mechanics, Inc., SEM and New York Academy of Science.

Curriculum Vitae for Carlos Estuardo Ventura:

Dr. Carlos Ventura is a Civil Engineer with specializations in structural dynamics and earthquake engineering. He has been a faculty member of the Department of Civil Engineering at the University of British Columbia (UBC) in Canada since 1992.  He is currently the Director of the Earthquake Engineering Research Facility (EERF) at UBC, and is the author of more than 480 papers and reports on earthquake engineering, structural dynamics and modal testing.   Dr. Ventura has conducted research about earthquakes and structural dynamics for more than thirtyh years. Three of his most significant contributions in recent years are the development and implementation of performance-based design methods for seismic retrofit of low rise school buildings, a unique seismic structural health monitoring program for bridges in BC, known as the BCSIMS project, and the first network-based earthquake early warning system for schools and public institutions in BC. These projects have contributed in a very significant manner to the seismic risk reduction efforts in BC. In addition to his academic activities, Dr. Ventura is a recognized international consultant on structural vibrations and safety of large Civil Engineering structures. The quality of his research work has been recognized by several national and international awards, as well as being appointed as member of the Canadian Academy of Engineering and of the Engineering Institute of Canada, and Fellow of Engineers Canada.  He is also a member of several national and international professional societies, advisory committees and several building and bridge code committees.
