Short Course:

 

"Designing for Wind Effects"

 

Dr. Ted Stathopoulos
Concordia University

and

Dr. Ahsan Kareem
University of Notre Dame

 

Synopsis:

The course will address the fundamentals of wind engineering related to design practice. Special emphasis will be placed to the design methodology for buildings and their cladding elements and the application of wind standard and codes of practice provisions in design. Both experimental and computational approaches will be outlined.

Puerto Rico especially is vulnerable to the impact of extreme winds in hurricanes as a large stock of buildings and other structures frequently fall in the path of hurricanes, which enhances their risk to failure.  Courses related to wind effects on structures are needed to address this challenge, but are not generally available to the engineering curriculum of most universities around the world at present. However, the effects of wind are extremely important for contemporary structural design. Therefore, this course intends to cover the lack of relevant advanced professional training with emphasis on practical aspects. Particularly, it will provide practical understanding of wind and how it interacts with structures and the corresponding loads and their effects; it will explain provisions of ASCE 7-05 and its correct interpretation; wind tunnel technology and introduction to computational tool.

The course will be of interest to engineers, researchers and academicians who work on relevant scientific research or design topics in research centers, universities, industry and government agencies.

He joined the Centre for Building Studies, Concordia University in 1979. He was promoted to the rank of Associate Professor in 1982 and to the rank of Professor in 1987. He has been Associate Director of the Centre for Building Studies for the period 1983-1995. In 1993, he was appointed Associate Dean of the Faculty of Engineering and Computer Science, a position he held until 1998, when he became Director of the Centre for Building Studies for the period 1998-2001. Since the beginning of 2003, he has been Associate Dean of the School of Graduate Studies, Concordia University. Dr. Stathopoulos has established an excellent teaching record at both the undergraduate and graduate levels and has also been active in the development of educational models. In 1997, he received the Concordia Council on Student Life Teaching Excellence Award and in 2006, the Alumni Award for Excellence in Teaching. He has an outstanding research record with more than 350 publications in refereed journals and conference proceedings. His work in the area of wind engineering and building aerodynamics has received national and international recognition. It forms the basis for wind design of low-rise buildings in the 1980, 1985, 1990, 1995 and 2005 National Building Code of Canada, and it has been partly included in the 1982 American National Wind Standard (later ASCE 7-88, 93, 95, 98, 02, 05) and in other standards as well. Dr. Stathopoulos has established the Building Aerodynamics Laboratory at the Centre for Building Studies and has developed, in cooperation with Dr. D. Surry of the University of Western Ontario, the so-called pneumatic-averaging technique for the measurement of area-averaged fluctuating wind pressures on buildings. This technique has been used routinely around the world. He received the Best Paper Award for the paper entitled “Wind-Tunnel Studies of Buildings and Structures” published in the ASCE Journal of Aerospace Engineering in 1996. Dr. Stathopoulos' research has been receiving continuously significant support by NSERC (operating, equipment, strategic, discovery, cooperative research and development grants), FCAR, later NATEQ / FQRNT (operating and equipment grants) and several other organizations. Dr. Stathopoulos has participated actively in numerous external bodies including the ASCE Standards Committee of Minimum Design Loads of Buildings and Other Structures. He has been elected America’s Regional Representative in the Executive Board of the International Association for Wind Engineering – IAWE (2003-07 and 2007- 11); and to the Board of Directors of the American Association for Wind Engineering – AAWE (2003-07). He has served on several ASCE bodies and chaired the Aerodynamics, the Experimental Analysis & Instrumentation, as well as the Wind Effects Committees of ASCE; he is a past member (Chair in 2000-01) and current Advisor of the Executive Committee of the Aerospace Division of ASCE. He is a member of the Executive Committee (Chair in 2007-09) of the Technical Council of Wind Engineering (TCWE) of ASCE. He has been invited and keynote speaker, chairman and rapporteur in short courses, national and international conferences taken place in Canada, the U.S.A., Europe, Japan and Australia. He has been consultant to numerous projects on issues related to wind-building interaction. He has acted as expert witness on cases related to wind-building interaction. He also has industrial experience, gained before his engagement in research. He has been honored by the American Association for Wind Engineering and he received the 1997 Engineering Award of the National Hurricane Conference for his “exhaustive studies leading to the adoption of the new ASCE-7 Minimum Design Loads for Buildings and Other Structures which is already leading to safer, more hurricane-resistant construction in many areas”. He received the ASCE Aerospace Division’s Outstanding Professional Service Award for the year 2004. He has been appointed Editor of the International Journal of Wind Engineering and Industrial Aerodynamics, as well as Editorial Board member of several prestigious journals in his field.
