Wind Actions Standard issued:
Dr. John Holmes chaired the Standards Australia sub-committee responsible
for the re-drafting of the Australian and New Zealand Standard for wind
loading that was issued in March 2011 as AS/NZS1170.2-2011.
2005, a "Guide to AS/NZS1170.2:2002" written by John Holmes
and Andrew King was published (http://www.1170actions.com).
This user-friendly guide to the Standard contains nine worked examples
and answers to frequently-asked questions. More than 1700 copies of
this book have now been sold. This book will be updated shortly to cover
the changes in the 2011 Standard
Consulting participates in investigations following Cyclone 'Yasi':
Dr. John Holmes joined a team assembled by the Cyclone Testing
Station, Townsville, and the Australian Building Codes Board, which
investigated the effects of severe Tropical Cyclone 'Yasi'. 'Yasi' crossed
the coast of North Queensland near Mission Beach in the early hours
of February 3rd 2011.
full report on the windfield and the damage produced both by wind forces
and storm surge in 'Yasi' is available from: http://www.jcu.edu.au/cts/research_reports/index.htm
John Holmes awarded a Davenport Medal: In July 2011 John Holmes
was awarded the Alan G. Davenport medal (Senior Award) by the International
Association for Wind Engineering (http://www.iawe.org).
He joined three other recipients of this award for 2011, which is named
after Professor Alan Davenport, the pioneer of modern wind engineering
who died in 2009. The award was given to John Holmes for 'his many practical
contributions to modeling and analyses of wind effects on structures
and development of wind load standards'.
Consulting collaborates with Synergetics: JDH
Consulting has recently formed a professional relationship with Synergetics
Pty. Ltd (http://www.synergetics.net.au),
an environmental engineering group based in West Melbourne that specializes
in the application of computational fluid dynamics (CFD) to a variety
of wind-related problems such as pollutant dispersion, and ventilation.
This will give JDH Consulting direct access to CFD expertise for possible
application to wind loads on structures.
Fricke assists JDH Consulting: Harry
Fricke assists on JDH Consulting projects on a part-time basis. Harry,
a graduate in aeronautical engineering, has had about 12 years experience
in wind engineering with MEL Consultants and Vipac Engineers and Scientists.
He has expertise in environmental wind effects in urban developments,
and has a strong interest in renewable energy. Harry has contributed
to a JDH project assessing the wind environment for the proposed new
Ararat Prison in Victoria and for a proposed multi-storey development
in Richmond, Victoria, and to assessment of wind loads on roof-mounted
wind tunnel opened in Hong Kong: A
new wind tunnel, designed by JDH Consulting for the Department
of Building and Construction at the City University of Hong Kong,
was first run in early 2007, and officially opened in December
2008. Of open circuit configuration, the wind tunnel was tailored
to fit into a very limited space available to the University. A
new enclosure for the wind tunnel was constructed on top of an
existing building. A large centrifugal blower provides the airflow,
with flow processing by a series of screens and a flow straightener
in a settling chamber. Other features of the wind tunnel are a
slotted roof to alleviate 'blockage' problems (i.e. flow problems
created by large models occupying the test section), and computer-controlled
roughness elements. The wind tunnel is now being used to investigate
wind loading and environmental problems in Hong Kong.
Holmes becomes Editor of an international journal:
In 2006 Dr. John Holmes was invited to become an Editor-in-Chief of the international
journal ‘Wind and Structures’ published by Techno Press of Korea.
This journal publishes issues every two months with fully-reviewed papers on
the structural engineering aspects of wind engineering (http://technopress.kaist.ac.kr).
on wind loading :
A general book on wind loading titled "Wind Loading of Structures"
authored by John Holmes, appeared in 2001, with the second edition published
in 2007 by Taylor and Francis of London, U.K. (http://www.taylorandfrancis.com).
The book (379 pages) is intended for practising design engineers, as
well as graduate and advanced undergraduate students. It has been used
for teaching at several American universities, including Louisiana State,
Texas Tech and the University of Texas. The second edition of "Wind
Loading of Structures" was published in 2007. Separate chapters
cover wind loads on various structures: low-rise buildings, tall buildings,
bridges, transmission lines, etc. The last chapter reviews six major
international wind loading codes and standards. An Appendix reviews
the extreme wind climate for 74 different countries, territories or
