Domes not based on icosahedrons or dodecahedrons

[Ashok Mathur]

Dear All,

There are only occasional discussions on such domes in this group.

Many years ago a Nezelander, John W. Rich used to actively build such domes and I had written about his work. Unfortunately he passed away many years ago but somebody has collected his work and made it available here  https://www.oocities.org/geodesicsnz/people.htm

There is a new paper by Dominika Bysiec ( attached to this post)  that discusses Octahedron domes based on two well known divisions  but with the twist that some domes use a single cross-section for all the struts, while the second model uses "optimized" cos-sections for different struts.

Using a mathematical modelling  described in the paper, it turns out that a single cross-section of the struts offers a stronger structure.

 Synergy at work!

Regards

Ashok

I've come up with some of those:

Those of you not already familiar with Hugh Kenner's book, Geodesic Math, has some very useful information on Octahedrals, Tetrahedrals, and several versions of elliptical domes in both Class 1 and 2.

 

I would also suggest you review information related to Catalan Solids.  They have some properties that are unique, interesting, and useful.
