Help Calculations Geodesic Dome.

[Antonio Rodrigues]

Hello Taff and other colleagues I need Excel spreadsheets or MATLAB scripts to calculate geodetic domes of N frequencies.

Please ask those who possess such calculations already made or to send me the formulas so I can develop the calculations.

Need to perform calculations of models of structures resembling the structures of the attached photos.

Thank you.

Antonio,

Here's a fully-developed javascript Geodesic calculation/display webpage that you should find useful:  http://bl.ocks.org/3057239

Note that, in "Index.html," the <script> lines specify two javascript files:

<script src="http://d3js.org/d3.v2.min.js?2.9.6"></script>
<script src="geodesic.js"></script>

Be sure to download both files, for your study.

Hello Antonio,
Are you plannning to build such structures for an aquaculture project?
It's certainly an interesting concept for taking advanage of offshore
waters. Because these fish pens are full geodesic spheres rather than
domes needing a flat truncation , you could take advantage of the
Mexican Method of geodesic subdivision. The number of unique strut
lengths for a class I dome equals the geodesic sphere's frequency. So
there is an economic advantage to that geometry. Maybe Hector
Hernandez has some comments on this...

I did wrote to ANTONIO, Guaymas Sonora is to close from Hermosillo 120 km only.
I am waiting for him yet.

Good your Idea Gerry :)

Hello Guys I intend to build such structures using composite materials and polyurethane foam to ensure buoyancy however need to perform their occupation of the initial structural calculations to form a stable structure. My biggest concern is with the connectors think about using what is known in Brazil as a system Unistrut one piece or even to join the parts together using a fixed structure that we have in the mold as each triangle will be using laminated glass fiber and its interior will make the injection of polyurethane foam at least I think to use so that the structure has a natural tendency of buoyancy and thus need fewer anchor points. I am enclosing a picture of the Unistrut system.

Hello,

You can buy connectors from www.sonostarhub.com.  They sell connectors that can be used with PVC pipe.  However, when I look at the connectors I can't help thinking that it should be possible to make your own connectors with a 3D printer.  I wonder if anyone here could post plans.  

I'm probably a few years late in responding.
