EMERGING JOINT TIME-FREQUENCY ANALYSIS TECHNIQUES FOR STRUCTURAL DYNAMICS
APPLICATIONS
Traditional Fourier analysis has been an important tool in scientific and
engineering applications for many years. However, it does not readily
capture non-stationary and local features, which are inherently present in
many dynamic phenomena. The lecture will focus on modern time-frequency
analysis techniques for capturing localized effects and evolutionary
frequency content by using wavelets and other related techniques .These
techniques can be construed as .mathematical microscopes. and
allow representation of complex problems with gradually
increasing degree of detail and resolution.. These techniques will be
presented with a historical perspective and in context with several
engineering applications; they will be used for analyzing both recorded
ground accelerograms and linear/nonlinear seismic responses of benchmark
structures. However, they are applicable as well to a plethora of other
themes. Related general topics and an entertaining intuition defying
problem will be also discussed.
Biographical Data
Professor Pol D. Spanos received his undergraduate degree in Mechanical
Engineering and Engineering Science from the Technical University in Athens,
Greece and his graduate education at CalTech, where he was awarded the MS
degree in Civil Engineering and the Ph.D. degree in Applied Mechanics,
with minors in Applied Mathematics and in Business Economics. His interests
are in the area of dynamics and vibrations, with emphasis on probabilistic,
non-linear, and signal-processing aspects; and with applications to
structural engineering, aerospace engineering, offshore engineering,
bio-mechanics, and composite materials. He has supervised the MS theses of
more than 70 students and the Ph.D. theses of more than 50 students. His
research findings have been disseminated in more than 300 papers in archival
journals, technical conferences, and industrial reports. He is
Editor-in-Chief of the International Journal of Non-Linear Mechanics, and
the Editor of the Journal of Probabilistic Engineering Mechanics. He is a
Fellow of ASCE, ASME, the American Academy of Mechanics, and the Alexander
von Humboldt Association. He has received numerous awards from
ASCE,ASME,The Alexander Von Houmboldt Foundation, and the International
Association for Structural Safety and Reliability He is a corresponding
member of the Academy of Athens (National Academy of Greece);a Foreign
Member of the Academy of Europe(Academia Europaea);a foreign Member of
the Indian National Academy of Engineering;and a Member of the
National Academy of Engineering (USA)
