Hi Everyone,
I just invented a new rotegrity dome that might interest you.
It is made entirely of 32" 2x6 pieces. Three pieces are attached with small plywood gussets to form identical struts which are uniquely combined to form a structural dome. Low cost and easy to assemble. Recycled lumber scraps repurposed into habitable shelter.
Here is a sketch designed with five point loads. Scalable by piece dimensions, a one trick pony.

Dear Charles,
Its a clever design with just 32 pieces for a large green house.
If you want other people to experiment with it, you need to provide the ecentricity ratios.

Regards

Ashok

82 degree intersecting ends throughout. Diameter is 6.75 times the piece length. Join three pieces with 5x16 plywood gussets to make struts with 82x30 compound angle at one end and 82x18 at the other end, each facing up. All identical. Assemble all the three strut triangles first and attach five triads to each other to form the top. A central post helps to lift as you build upward. Five of the triads are truncated two thirds at bottom.
Simple assembly. Thank you for your interest, Ashok.
Affordable if recycling and repurposing.

Note: Gussets on opposite side of strut intersection.
