Geodesic report

[andrew777]

Hello:

I am interested rigid tensegrity domes many people who have written
about them mention a geodesic report by Amy C. Edmunson

After searching intensively on the Internet, I have failed to find an
article written about Buckminster Fuller's rigid tensegrity domes.
The article is "Geodesic report : The De-resonated Tensegrity Dome -
Design and Analysis". If you have access to this report, could you
please send me a copy.

A fellow member of geodesic help,

For readers who may be searching through their library, the full reference is:

 

Edmondson, Amy
"Geodesic Reports: The Deresonated Tensegrity Dome"
Synergetica; Journal of Synergetics, Volume 1 , Number 4
November, 1986

[andrew777]

Hello TaffGoch:

I have the full reference already, however, the article is not at the
libraries in my area. If you know the particular library where I can
find it, I will contact them.

But if you have the article please let me know.

Based on my previous post I have exhausted conventional options.

I need someone who has the article or knows where to find it.

As I said before, any help will be appreciated.

Andrew

Andrew,

 

I suspected that you had the full reference info. I posted it for other readers, who might be inclined to look through their personal library, and could benefit from having the full reference.

 

"Synergetica, The Journal of Synergetics," was fairly short-lived (5-6 years,) not to be mistaken for "Synergetica Journal" (1991,) which was also short-lived (even more-so.)

 

Short-lived journals are, indeed, less likely to be subscribed to by public or institutional libraries. I hope you get a good lead from your inquiry.

While searching online for Edmonson's article, I stumbled across a reference I had not seen before. While not the article in question, it is a mathematically-intensive analysis of tensegrity structures. (Way over my head, by a long shot!)

 

"An Introduction to the Mechanics of Tensegrity Structures"

Hi  Andrew

Please contact Joe Clinton. Ask Joe about Dick Boyt and Dick's rotegrity sphere. Joe will be able to help you on this, I am sure. The rotegrity is a breakthrough structure, Joe says. It sounds like what you are asking about.

http://snec.cjfearnley.com/snec.meeting.2003.06.html

I also am equally sure tensegrity.wikispace can help locate the info you need. Go here.

I found this for you to check this out, too.

http://www.bioarchitettura-rivista.it/Arretrati/n39-40/Sfere.htm

"The Rotegrities submitted by Joseph Clinton (employee of NASA in the 70s the first to publish values of factors 1 and rope on Domebook Domebook 2) at the conference 'SNEC 2003' held in Oswego, New York, are similar in geometry to the BGS Roelofs but to make use of rivets connecting. The structures tensegrali rotated (just 'rotegrity') are obtained by rotating the elements of any construction tensegrale around its center point.According to Clinton Rotegrity is a term introduced in 1970 by Richard Boyt wrote in his unpublished Rotegrity: An Alternate Method of Spanning Space with a compound curvature."

Hello Dick and all:

Thank you all, some of the info that some of you related seems
relevant to what I'm interested in. What is the e-mail address of Joe
Clinton?
I found another reference to an article that seems interesting:
"Relation between eccentricity and engagement length" O. Baverel. It
is about nexorades the cousins to
Reciprocal frames and de-resonated tensegrity. Does anyone have access
to that article?

Best regards,

Andrew

If reciprocal frames and nexorades are on-topic, might some of these SketchUp models be of any interest?

http://sketchup.google.com/3dwarehouse/cldetails?mid=1f33552966b6f22224e5217d8a2e013a&num=50&scoring=d

 

There may be dozen-or-so pertinent models. (I know one is a nexorade.)

[TaffGoch]

 

I assume you've already seen the Nexus Network Journal article, "Nexorades Based on Regular Polyhedra"

http://books.google.com/books?id=VbKr9u2oRSIC&pg=PA281#v=onepage&q&f=false

[Richard Fischbeck]

I can forward a message to Joe for you if you want. Or I can send his address off list to you.

Andrew,

 

Thanks for reminding me that I need to get back to a project that I've had "on the back burner," but keep neglecting.

Hi Geodes,

its new location... (the structure is carbon fibre infusion)

Andrew,
 
If you use Google search, for the title, "Relation between Eccentricity and Engagement"...
http://www.google.com/search?hl=en&lr=&safe=off&as_qdr=all&q=+site:composites.enpc.org+%22Relation+between+Eccentricity+and+Engagement%22&sa=X&ei=JTtsTPyXAsiAnQeukbCyAg&ved=0CAIQqAQwAg
...you will find several chapters, all PDF files. (This is apparently a PhD thesis.)

When you click on one of the results, you'll be redirected to a French introductory page, instead. You can continue past this intro page, by logging in as a guest; clicking the button labelled, "Connexion en tant qu'invité"

You will then be allowed to view the PDF files. Of particular interest are the following chapters:

http://composites.enpc.org/moodle/file.php/9/chapt5.pdf

BTW, you may need to have "accept cookies" turned ON, for the guest
login to work.

Andrew,

 

Once you've logged in to the above-referenced French website, as a guest, you can get to several other PDF files (regarding nexorades):

 

http://composites.enpc.org/moodle/file.php/9/chapt4.pdf 

(Missing from Google search results. Along with the chapters revealed by the Google search, this will provide to you the complete thesis.)

 

http://composites.enpc.org/moodle/file.php/9/nexoradeijss2000.pdf

http://composites.enpc.org/moodle/file.php/9/nexorade.pdf (French)

http://composites.enpc.org/moodle/file.php/9/IconexA3.pdf (French)

 

I've saved copies of all the nexorade PDF files to my hard-drive, as they are of interest to me, as well. In fact, I've been modeling nexorades, without knowing them by that name! (Biagio is also actively interested in these space structures.)

 

-Taff

[Andrew Jackson]

Taff and all:

I have previously googled you and Biagio in my previous searches for references on nexorades and deresonated tensegrities.
Nice work on your geodesic dome drawings and tutorials as well as your reciprocal frame dome's or nexorades. Maybe you will
show me how to draw a reciprocal frame in sketchup. I know sketchup and autocad. I am happy that you now know the name of
what you been drawing. lol
That PhD thesis is great information, that should help us to mathematically derived the structures.

Thanks again for your help,

Andrew

I've found that the article, "Nexorades Based on Regular Polyhedra,"
as a PDF, is also available at the French website.

This is going to be an experiment, to see if I can attach the PDF
files to this discussion.

It may not work, so please excuse any extraneous messages.

This appendix completes the PhD thesis document, "Relation between Eccentricity and Engagement Length"

[TaffGoch]

This is the separate document, "Nexorades Based on Regular Polyhedra"

[andrew777]

Taff and all:

Beginning to read "Relation between eccentricity and engagement
length", introduction it is a gold mine of information.
Check out formex algebra and formian software, is supposed to do
Nexorades and free-form spatial structures computationally and
graphically by computer. I hope the whole group reads the PhD thesis
and discusses it as a learning experience. I'm ready to learn.

This is the separate summary document, "Nexorades", by the author of the above article (Olivier Baverel,) as it appeared in the "International Journal of Space Structures," Vol.15, No.2, 2000

[TaffGoch]

This is the article, ""Formfinding of Nexorades using Genetic Algorithms", by Olivier Baverel (2003)

 

That covers all the nexorade documents I could find online (except for two French poster presentations that summarize the contents of the above PDFs -- nothing new.)

 

That should be plenty to chew on for a while....

[TaffGoch]

 

Another article, "Nexorade: A Structure for Free-Form Architecture" (2006)...

 

http://www.irbnet.de/daten/iconda/CIB10869.pdf

 

...but no dramatic revelations over previously-posted articles.
