In terms of the strapping, I'd look at the stuff from Signode - they do a very strong, very cheap steel strap with holes punched about every half inch. Corrosion resistant etc. We used it back in the day for doing geodesic dome work - goes over the nodes, really tightens things up.
If you look up Will Fidroeff's dome work, you'll see their T-beam design which is very good in terms of fast build of well insulated buildings. I'm not sure it's practical for Hexayurts, which are more-or-less inherently stressed skin structures, but you might want to look at it and have a think about if there's anything to learn. It's online in various places, used to be called econodome.
